Abstract (sommario):

The literature has customarily defined interaction between pictured objects in two ways. First, interaction has been defined as simply a conjoined union or physical touching of objects within a given picture scene. The second definition portrays interaction as predetermined action or implied motion between the pictured objects. Researchers typically assume these two modes of defining interaction as essentially equivalent. Generally stated, the purpose of this study was to uncover the effect that implied motion has on the processing of visual information. A factorial design was conducted with dependent variables being imageability, nameability, and recall of pictured objects. Independent variables were implied motion and viewing time. Results showed that implied motion pictures presented at a short viewing time were more nameable and better recalled than stationary pictures presented at a short viewing time. But when subjects were given more time to view visual information, implied motion and stationary pictures were equally nameable and recalled. The results indicate that when visual information is presented for a sufficiently short time, implied motion heightens the availability of a verbal code.

Abstract (sommario):

Aiming at the problem that it is difficult to balance the speed and accuracy of human behaviour recognition, this paper proposes a method of motion recognition based on random projection. Firstly, the optical flow picture and Red, Green, Blue (RGB) picture obtained by the Lucas-Kanade algorithm are used. Secondly, the data of optical flow pictures and RGB pictures are compressed based on a random projection matrix of compressed sensing, which effectively reduces power consumption. At the same time, based on random projection compression data, it can effectively find the optimal linear representation to reconstruct training samples and test samples. Thirdly, a multichannel 3D convolutional neural network is proposed, and the multiple information extracted by the network is fused to form an output recognizer. Experimental results show that the algorithm in this paper significantly improves the recognition rate of multicategory actions and effectively reduces the computational complexity and running time of the recognition algorithm.

Abstract (sommario):

This article highlights that the adage, a picture is worth a thousand words, is a flawed understatement. Our memories, knowledge, and opinions rely heavily on pictures. Words can only provide an explanation to information contained in a good picture. Time always moves forward, but a picture allows us to look back to some prior moment in time. Photography, which means writing with light, would require replacing the artist’s paper with a chemically coated screen, exposing the screen to the image, and then stabilizing the resulting picture. The first practical photographic process was announced in France in 1839 by Louis Daguerre, who had achieved fame as a designer of theater stages and lighting effects. George Eastman built a magnificent Colonial Revival Mansion on East Avenue in Rochester in 1905. It is a National Historic Landmark and is chartered by the State of New York as the International Museum of Photography and Film. It displays a rare collection of photographs, cameras, projectors, books, and motion pictures.

Abstract (sommario):

We study the relation between two evolution pictures that are currently considered for totally constrained theories. Both descriptions are based on Rovelli’s evolving constants approach, where one identifies a (possibly local) degree of freedom of the system as an internal time. This method is well understood classically in several situations. The purpose of this paper is to further analyze this approach at the quantum level. Concretely, we will compare the (Schrödinger-like) picture where the physical states evolve in time with the (Heisenberg-like) picture in which one defines parametrized observables (or evolving constants of the motion). We will show that in the particular situations considered in this paper (the parametrized relativistic particle and a spatially flat homogeneous and isotropic spacetime coupled to a massless scalar field) both descriptions are equivalent. We will finally comment on possible issues and on the genericness of the equivalence between both pictures.

Abstract (sommario):

One phenomenon dominates the history of motion pictures: at one time or another, a single country has emerged as the most creative and vital source of film making on the international scene. It is almost as if a spotlight moved across the stages of the world, pausing now here, now there, to illuminate the work of an entire group of artists. This was perhaps understandable in the Soviet Union during the mid-Nineteen-Twenties, when a new government actively encouraged experimentation in all the arts, and particularly the art of the motion picture.

Abstract (sommario):

ABSTRACTSome observations on using motion pictures to teach Business English. THE USE of motion pictures or other captioned films as part of teaching English as a foreign language has markedly increased in recent years in China. Because of this, we undertook a four-year experiment to determine how effective the use of English-language movies has been in the teaching of business. From this experiment it became clear that a cavalier use of movies in effect misused them. The appropriate and effective use of motion pictures requires a range of elements: (1) movies that are at one and the same time educational, informative, and entertaining; (2) a workbook linked to such movies that enables students to get ready beforehand; (3) most importantly, a range of classroom activities to induce and elicit timely and optimal output from the students, so as to make talking and writing about communication easier and more effective. Activities such as dubbing, story retelling, acting, discussing, debating, and role playing are only a few of the effective techniques a teacher can employ to engage the students.

Abstract (sommario):

The surface electromyography (sEMG) signal is widely used as a control source of the upper limb exoskeleton rehabilitation robot. However, the traditional way of controlling the exoskeleton robot by the sEMG signal requires one to specially extract and calculate for complex sEMG features. Moreover, due to the huge amount of calculation and individualized difference, the real-time control of the exoskeleton robot cannot be realized. Therefore, this paper proposes a novel method using an improved detection algorithm to recognize limb joint motion and detect joint angle based on sEMG images, aiming to obtain a high-security and fast-processing action recognition strategy. In this paper, MobileNetV2 combined the Ghost module as the feature extraction network to obtain the pretraining model. Then, the target detection network Yolo-V4 was used to estimate the six movement categories of the upper limb joints and to predict the joint movement angles. The experimental results showed that the proposed motion recognition methods were available. Every 100 pictures can be accurately identified in approximately 78 pictures, and the processing speed of every single picture on the PC side was 17.97 ms. For the train data, the mAP@0.5 could reach 82.3%, and mAP@0.5–0.95 could reach 0.42; for the verification data, the average recognition accuracy could reach 80.7%.

Abstract (sommario):

This article proposes a new algorithm applicable to H.264 based on motion vector coding length and high-pixel accuracy filter operator instead of linear interpolation. After half-pixel accuracy motion estimation, a high accuracy motion estimation can be calculated with the intermediate results. This algorithm can achieve high accuracy estimation and compensation while decreasing algorithm complexity. The computer simulation results show that when the new proposed algorithm for 1/8-pixel accuracy is used in QCIF, CIF, CCIR format pictures, total computing time reduces more than 20% and computing time used for fractional-pixel motion estimation reduces more than 50% while coding length only increases less than 10% and PSNR-Y is approximately equal.

Abstract (sommario):

Programmed retinal picture investigation is a significant screening device for simple identification of eye infections like diabetic retinopathy, glaucoma. Hemorrhage (HE) identification is one of the significant strides in programmed extraction in Diabetic Retinopathy (DR) ailment. The manual strategy evaluated by clinicians is a tedious and asset concentrated procedure. Programmed retinal picture examination gives a prompt recognition and portrayal of retinal highlights preceding a pro investigation. Current HE detection techniques suffer from impractically-high computation time. In this research work, presented a technique to automatically detect HE. This paper proposes an efficient motion pattern generation algorithm to detect HE. The novelty of this method is to reduce the dimensional space based on image resolutions thus, enhances to speedup of the HE detection. The proposed strategy was executed in MATLAB and assessed both ordinary and unusual retinal pictures utilizing openly accessible MESSIDOR dataset. The proposed strategy accomplished better execution estimates when contrast with other cutting edge strategies. This automated method helps ophthalmologists in the screening process of DR.

Abstract (sommario):

Recently, the use of different social media platforms such as Twitter, Facebook, and WhatsApp have increased significantly. A vast number of static images and motion frame pictures posted on such platforms get stored in the device folder making it critical to identify the social network of the downloaded images in the android domain. This is a multimedia forensic job with major cyber security consequences and is said to be accomplished using unique traces contained in picture material (SNs). Therefore, this proposal has been endeavoured to construct a new framework called FusionNet to combine two well-established single shared Convolutional Neural Networks (CNN) to accelerate the search. Moreover, the FusionNet has been found to improve classification accuracy. Image searching is one of the challenging issues in the android domain besides being a time-consuming process. The goal of the proposed network's architecture and training is to enhance the forensic information included in the digital pictures shared on social media. Furthermore, several network designs for the categorization of WhatsApp pictures have been compared and this suggested method has shown better performance in the comparison. The proposed framework's overall performance was measured using the performance metrics.

Abstract (sommario):

Cameras play a prominent role in the context of 3D data, as they can be designed to be very cheap and small and can therefore be used in many 3D reconstruction systems. Typical cameras capture video at 20 to 60 frames per second, resulting in a high number of frames to select from for 3D reconstruction. Many frames are unsuited for reconstruction as they suffer from motion blur or show too little variation compared to other frames. The camera used within this work has built-in inertial sensors. What if one could use the built-in inertial sensors to select a set of key frames well-suited for 3D reconstruction, free from motion blur and redundancy, in real time? A random forest classifier (RF) is trained by inertial data to determine frames without motion blur and to reduce redundancy. Frames are analyzed by the fast Fourier transformation and Lucas–Kanade method to detect motion blur and moving features in frames to label those correctly to train the RF. We achieve a classifier that omits successfully redundant frames and preserves frames with the required quality but exhibits an unsatisfied performance with respect to ideal frames. A 3D reconstruction by Meshroom shows a better result with selected key frames by the classifier. By extracting frames from video, one can comfortably scan objects and scenes without taking single pictures. Our proposed method automatically extracts the best frames in real time without using complex image-processing algorithms.

Abstract (sommario):

Background: A breast-specific photoacoustic imaging (PAI) system prototype equipped with a hemispherical detector array (HDA) has been reported as a promising system configuration for providing high morphological reproducibility for vascular structures in living bodies. Methods: To image the vasculature of human limbs, a newly designed PAI system prototype (PAI-05) with an HDA with a higher density sensor arrangement was developed. The basic device configuration mimicked that of a previously reported breast-specific PAI system. A new imaging table and a holding tray for imaging a subject's limb were adopted. Results: The device’s performance was verified using a phantom. Contrast of 8.5 was obtained at a depth of 2 cm, and the viewing angle reached up to 70 degrees, showing sufficient performance for limb imaging. An arbitrary wavelength was set, and a reasonable PA signal intensity dependent on the wavelength was obtained. To prove the concept of imaging human limbs, various parts of the subject were scanned. High-quality still images of a living human with a wider size than that previously reported were obtained by scanning within the horizontal plane and averaging the images. The maximum field of view (FOV) was 270 mm × 180 mm. Even in movie mode, one-shot 3D volumetric data were obtained in an FOV range of 20 mm in diameter, which is larger than values in previous reports. By continuously acquiring these images, we were able to produce motion pictures. Conclusion: We developed a PAI prototype system equipped with an HDA suitable for imaging limbs. As a result, the subject could be scanned over a wide range while in a more comfortable position, and high-quality still images and motion pictures could be obtained.

Abstract (sommario):

ABSTRACTElectronic picture storybooks often include motion pictures, sounds, and background music instead of static pictures, and hotspots that label/define words when clicked on. The current study was designed to examine whether these additional elements aid word learning and story comprehension and whether effects accumulate making the animated e-book that also includes hotspots the most promising device. A sample group of 136 4- and 5-year-old kindergarten children were randomly assigned to one of four conditions: static e-books, animated e-books, interactive animated e-books, and a control group. In experimental conditions, four on-screen stories were each presented four times during a 4-week intervention period. Children in the control condition played nonliteracy related computer games during the same time. In all conditions, children worked independently with the computer programs. Strong treatment effects were found on target vocabulary originating from the story. Pupils gained most in vocabulary after reading interactive animated e-books, followed by (noninteractive) animated e-books and then static e-books. E-books including animations and interactivity were neither beneficial nor detrimental for story comprehension. Findings suggest that electronic storybooks are valuable additions in support of the classroom curriculum with interactive animated e-books being the best alternative.

Abstract (sommario):

AbstractThe following article is based on a presentation given as part of Symposium X—Frontiers of Materials Research on December 4, 2002, at the 2002 Materials Research Society Fall Meeting. The cinema is just over 100 years old. From the beginning of motion pictures in the mid-1890s, the materials used for films have been at the heart of cinema technology. The material first used was cellulose nitrate film—unrivaled in its mechanical, physical, and aesthetic qualities, and also dangerously flammable. In the 1950s, cellulose nitrate was replaced, for safety reasons, by cellulose triacetate. Today, polyester film is widely used; nevertheless, the fact remains that the majority of the world's film heritage exists on two main material formats, cellulose nitrate and cellulose triacetate, both of which decay over time. Film archivists are engaged in a race to save historic film footage from being lost forever. Digital technology, now widely used in cinema, does not resolve the issue of the long-term preservation of films because digital formats are still evolving. This article discusses the materials used in motion-picture technology over the years, the mechanisms active in film decomposition, and international efforts to preserve and restore historic films.

Abstract (sommario):

In this article, a two-degree-of-freedom system consisting of two pendulums with magnets embedded in a variable magnetic field is investigated experimentally and numerically. Pivots of the pendulums are coupled by an elastic element. The magnetic interaction originates from permanent magnets, mounted at free ends of the pendulums and current-powered air coils underneath. A novel model for the magnetic force is proposed and verified experimentally. Nonlinear dynamics of the system is examined by means of time series, bifurcation diagrams, phase portraits, and Poincaré sections. Regions of chaotic and regular motion are predicted numerically and justified experimentally. Multiperiodic motion and coexisting solutions are detected, and pictures in basins of their attraction are reported, among other.

Abstract (sommario):

With the development of science and technology, the introduction of virtual reality technology has pushed the development of human-computer interaction technology to a new height. The combination of virtual reality and human-computer interaction technology has been applied more and more in military simulation, medical rehabilitation, game creation, and other fields. Action is the basis of human behavior. Among them, human behavior and action analysis is an important research direction. In human behavior and action, recognition research based on behavior and action has the characteristics of convenience, intuition, strong interaction, rich expression information, and so on. It has become the first choice of many researchers for human behavior analysis. However, human motion and motion pictures are complex objects with many ambiguous factors, which are difficult to express and process. Traditional motion recognition is usually based on two-dimensional color images, while two-dimensional RGB images are vulnerable to background disturbance, light, environment, and other factors that interfere with human target detection. In recent years, more and more researchers have begun to use fuzzy mathematics theory to identify human behaviors. The plantar pressure data under different motion modes were collected through experiments, and the current gait information was analyzed. The key gait events including toe-off and heel touch were identified by dynamic baseline monitoring. For the error monitoring of key gait events, the screen window is used to filter the repeated recognition events in a certain period of time, which greatly improves the recognition accuracy and provides important gait information for motion pattern recognition. The similarity matching is performed on each template, the correct rate of motion feature extraction is 90.2%, and the correct rate of motion pattern recognition is 96.3%, which verifies the feasibility and effectiveness of human motion recognition based on fuzzy theory. It is hoped to provide processing techniques and application examples for artificial intelligence recognition applications.

Abstract (sommario):

In recent times face tracking and face recognition have turned out to be increasingly dynamic research field in image processing. This work proposed the framework DEtecting Contiguous Outliers in the LOw-rank Representation for face tracking, in this algorithm the background is assessed by a low-rank network and foreground articles can be distinguished as anomalies. This is suitable for non-rigid foreground motion and moving camera. The face of a foreground person is caught from the frame and then it is contrasted and the speculated pictures stored in the dataset. Here we used Viola-Jones algorithm for face recognition. This approach outperforms the traditional algorithms on multimodal video methodologies and it works adequately on extensive variety of security and surveillance purposes. Results on the continuous demonstrate that the proposed calculation can correctly obtain facial features points. The algorithm is relegate on the continuous camera input and under ongoing ecological conditions.

Abstract (sommario):

A simplified bubble model and its solver optimization method are proposed to solve the problem of poor realistic simulation and complex solutions for bubble-motion behavior in water. Firstly, the internal velocity of the bubble was avoided, and the bubble model was established by only considering the net flux of the inlet and outlet bubbles, which reduced the computational complexity. The bubble constraint was then introduced into the motion equation of water, and the mixed Euler–Lagrangian method was used to solve it. FLIP particles tracked the bubble position, velocity, and deformation, and the mesh updated the vector field. At the same time, the viscosity term was simplified. Finally, it was combined with implicit incompressible SPH particles to achieve the purpose of volume correction. The experimental results show that the method in this paper can present a simulation effect of bubbles in water with rich detail and a realistic sense, whether compared with actual pictures or with existing methods.

Abstract (sommario):

This study proposes a lightweight solution to estimate affine parameters in affine motion compensation. Most of the current approaches start with an initial approximation based on the standard motion estimation, which only estimates the translation parameters. From there, iterative methods are used to find the best parameters, but they require a significant amount of time. The proposed method aims to speed up the process in two ways, first, skip evaluating affine prediction when it is likely to bring no encoding efficiency benefit, and second, by estimating better initial values for the iteration process. We use the optical flow between the reference picture and the current picture to estimate quickly the best encoding mode and get a better initial estimation. We achieve a reduction in encoding time over the reference of half when compared to the state of the art, with a loss in efficiency below 1%.

Abstract (sommario):

The combination of gesture recognition and aerospace exploration robots can realize the efficient non-contact control of the robots. In the harsh aerospace environment, the captured gesture images are usually blurred and damaged inevitably. The motion blurred images not only cause part of the transmitted information to be lost, but also affect the effect of neural network training in the later stage. To improve the speed and accuracy of motion blurred gestures recognition, the algorithm of YOLOv4 (You Only Look Once, vision 4) is studied from the two aspects of motion blurred image processing and model optimization. The DeblurGanv2 is employed to remove the motion blur of the gestures in YOLOv4 network input pictures. In terms of model structure, the K-means++ algorithm is used to cluster the priori boxes for obtaining the more appropriate size parameters of the priori boxes. The CBAM attention mechanism and SPP (spatial pyramid pooling layer) structure are added to YOLOv4 model to improve the efficiency of network learning. The dataset for network training is designed for the human–computer interaction in the aerospace space. To reduce the redundant features of the captured images and enhance the effect of model training, the Wiener filter and bilateral filter are superimposed on the blurred images in the dataset to simply remove the motion blur. The augmentation of the model is executed by imitating different environments. A YOLOv4-gesture model is built, which collaborates with K-means++ algorithm, the CBAM and SPP mechanism. A DeblurGanv2 model is built to process the input images of the YOLOv4 target recognition. The YOLOv4-motion-blur-gesture model is composed of the YOLOv4-gesture and the DeblurGanv2. The augmented and enhanced gesture data set is used to simulate the model training. The experimental results demonstrate that the YOLOv4-motion-blur-gesture model has relatively better performance. The proposed model has the high inclusiveness and accuracy recognition effect in the real-time interaction of motion blur gestures, it improves the network training speed by 30%, the target detection accuracy by 10%, and the value of mAP by about 10%. The constructed YOLOv4-motion-blur-gesture model has a stable performance. It can not only meet the real-time human–computer interaction in aerospace space under real-time complex conditions, but also can be applied to other application environments under complex backgrounds requiring real-time detection.

Abstract (sommario):

Squeeze film dampers (SFDs) reduce rotor vibrations and control dynamic instabilities in turbomachinery. Depending on damper geometry and operating conditions, the kinematics of journal motion can induce air ingestion and entrapment, produce lubricant vapor cavitation, or both. Air ingestion is the most common condition found in open ended dampers due to the low levels of external pressurization used in practice. The degrading effect of air entrapment on damper performance not only defies predictive models but also constrains the design of SFDs to a costly trial and error process based on prior experience. The present measurements correlate for the first time dynamic squeeze film pressures and pictures of the flow field with the air volume content in the lubricant mixture of a damper performing circular centered motion. The photographs of the flow field at key instances of journal motion show the development of a non-homogeneous flow with large striated cavities of air that persist even in the regions of positive (above ambient) dynamic pressures.

Abstract (sommario):

Most anti-shake technologies can compensate the hand shake when taking a static picture. When people use the camera in the dim environment, the shutter opening time will be extended to increase exposure. However, the hand shake will cause the photos blurry if the shutter opening time was too long. The hand shake problem is even more serious when people doing the dynamic image recording. In the past years, the mobile phones with the digital camera and portable video camera were developed vigorously. Taking pictures and recording dynamic image have become the basic functions of mobile phones since the development of the 3G mobile phone. While the specifications of cameras become high resolution and high magnification optical zoom, the traditional electronic anti-shake technology will not be applied in the digital camera because of the large amount of computing power. It is also difficult to apply the optical anti-shake technology in thin 3C products because the volume of optical anti-shake module is too large. Thus, developing a new anti-shake technology which can be applied in the thin 3C products to enhance the photo and video quality is very important. In this paper, the image processing technologies will be applied to calculate the motion signal. Then, the voluntary and involuntary motion signals will be separated by the signal separation algorithm, and finally the dynamic image will be reconstruction by compensating the involuntary shake of each frame to enhance the quality of the dynamic image.

Abstract (sommario):

The extremely short life cycle and the rapid decay in revenues after opening coupled with the rapid and frequent introduction of new competitive products makes the timing of new product introductions in the motion picture industry critical, particularly during the high-revenue Christmas and summer seasons. Each studio wants to capture as much of the season as possible by opening early in the season. At the same time, each wants to avoid head-to-head competition. The authors model competition between two motion pictures in a share attraction framework and conduct an equilibrium analysis of the product introduction timing game in a finite season. The following three different equilibrium configurations emerge: (1) a single equilibrium with both movies opening simultaneously at the beginning of the season, (2) a single equilibrium with one movie opening at the beginning of the season and one delaying, and (3) dual equilibria, with either movie delaying opening. A key factor is the product life cycle, which can be captured well with a two-parameter exponential decline. The authors relate the life-cycle parameters to these possibilities with the general result that the weaker movie may be forced to delay opening. These results are related to case studies of the opening of recently released movies. A statistical analysis of the 1990 summer season in North America provides support for the conclusions and suggests that current release timing decisions can be improved. The authors discuss the rationale of “avoiding the competition” in the general context of product introduction timing.

Abstract (sommario):

Before 1965 and the introduction of the .rst of.cial American combat troops, the political unrest and revolutionary insurgency in Vietnam had already appeared in nearly a dozen Hollywood .lms. Yet while the anti-communist politics of these productions was predictable, it would be a mistake to view them as mere vehicles for Cold War propaganda. Although they served that obvious function, early American filmmakers who set their pictures in Vietnam also constructed the area as a childlike place in need of U.S. tutelage and instruction. At the same time, Vietnam became, by the 1950s, ironically transformed into a site of contestation over American values, especially with respect to race and gender. Drawing on rare prints of these early motion pictures, as well as numerous archival documents, this article spotlights the Indochinese conflict that was screened in the decades before Hollywood, in the 1970s and 1980s, began to perhaps forever reimage the war in American memory.

The specimen was picked by the use of Cochran with the standard deviation of 0.4.5% 470 students. The outcomes demonstrated that members can isolate in two sections dynamic and idle style which the vast majority of interviewees are willing toward a dormant style of relaxation time. While the significant piece of understudies' chance is spent on the utilization of innovative devices conveniently. For sure, watching satellite motion pictures and arrangement, investing energy in broad daylight talk rooms, PC amusements, are only a misuse of understudies' opportunity.

This paper discusses the application of Eye Tracking (ET) technologies for researchers to understand a driver’s perception of signage at the highway work zone. Combining ET within a screen-based motion pictures and a driving simulator, the team developed an analytical method that allowed designers to evaluate signage design. Two experiments were set up to investigate how signage design might affect a driver’s visual attention and interaction under various environmental complexities and glare conditions. The study explores the visual perception related to several spatial features, including signage modality, scene complexity, and color schemes. The ET method utilizes total fixation time and time to first fixation data to evaluate the effectiveness of signage presented through screen-based video and a driving simulator.

Electromagnetically induced transparency (EIT) can make an otherwise opaque medium transparent by utilizing quantum coherence. EIT has attracted great interest since the 1990s for its wide applications in metrology, nonlinear and quantum optics, and quantum information science. We present a review on spectral line narrowing mechanisms in EIT-related systems, accounting for linewidths much narrower than expected from the standard mechanisms of Doppler broadening, transit time broadening, magnetic field inhomogeneity and power broadening. Topics covered include Dicke narrowing, atomic-motion-induced Ramsey narrowing, motional narrowing, density narrowing, laser induced narrowing and power-broadening-free resonance. Intuitive pictures are provided to describe the essential physics of each mechanism.

Abstract (sommario):

Motion pictures taken at Duck Creek, a clear stream 6.5 m wide and 35 cm deep near Pinedale, Wyoming, provide detailed, quantitative information on both the modes of motion of individual bedload particles and the collective motions of large numbers of them. Bed shear stress was approximately 6 Pa (60 dynes cm−2), which was about twice the threshold for movement of the 4 mm median diameter fine gravel bed material; and transport was almost entirely as bedload. The displacements of individual particles occurred mainly by rolling of the majority of the particles and saltation of the smallest ones, and rarely by brief sliding of large, angular ones. Entrainment was principally by rollover of the larger particles and liftoff of the smaller ones, and infrequently by ejection caused by impacts, whereas distrainment was primarily by diminution of fluid forces in the case of rolling particles and by collisions with larger bed particles in the case of saltating ones. The displacement times averaged about 0.2−0.4 s and generally were much shorter than the intervening repose times. The collective motions of the particles were characterized by frequent, brief, localized, random sweep-transport events of very high rates of entrainment and transport, which in the aggregate transported approximately 70% of the total load moved. These events occurred 9% of the time at any particular point of the bed, lasted 1–2 s, affected areas typically 20–50 cm long by 10–20 cm wide, and involved bedload concentrations approximately 10 times greater than background. The distances travelled during displacements averaged about 15 times the particle diameter. Despite the differences in their dominant modes of movement, the 8–16 mm particles typically travelled only about 30% slower during displacement than the 2–4 mm ones, whose speeds averaged 21 cm s−1. Particles starting from the same point not only moved intermittently downstream but also dispersed both longitudinally and transversely, with diffusivities of 4.6 and 0.26 cm2 s−1, respectively. The bedload transport rates measured from the films were consistent with those determined conventionally with a bedload sampler. The 2–4 mm particles were entrained 6 times faster on finer areas of the bed, where 8–16 mm particles covered 6% of the surface area, than on coarser ones, where they covered 12%, even though 2–4 and 4–8 mm particles covered practically the same percentage areas in both cases. The 4–8 and 8–16 mm particles, in contrast, were entrained at the same rates in both cases. To within the statistical uncertainty, the rates of distrainment balanced the rates of entrainment for all three sizes, and were approximately proportional to the corresponding concentrations of bedload.
