Abstract:

This paper emphasizes on various aspects of human factors engineering. Researchers believe that superior design creates demand for new products. According to a human factor engineer, a design succeeds because it improves the user’s experience, defined in this case as time to complete a procedure. Metaphase Design’s new paintbrush for Shur-Line looks cool and uses human factors research to improve control and reduce forearm stress. Studies show that a parent’s voice wakes children better than an alarm during a fire. Hospitals and clinicians will pay a premium so they can work faster and more efficiently. Today, a growing number of designers have embraced human factors techniques, while extending those techniques to include emotion and cognition to shape the experience of the user. There is a need for a powerful user experience along with good looks for a product to be successful. The paper concludes that despite all the emphasis on human factors, personality and product profiling, and collaboration, the thinking behind it remains a very human and very personal vision.

Abstract:

Many computer vision applications need keypoint correspondence between images under different view conditions. Generally speaking, traditional algorithms target applications with either good performance in invariance to affine transformation or speed of computation. Nowadays, the widely usage of computer vision algorithms on handle devices such as mobile phones and embedded devices with low memory and computation capability has proposed a target of making descriptors faster to computer and more compact while remaining robust to affine transformation and noise. To best address the whole process, this paper covers keypoint detection, description and matching. Binary descriptors are computed by comparing the intensities of two sampling points in image patches and they are matched by Hamming distance using an SSE 4.2 optimized popcount. In experiment results, we will show that our algorithm is fast to compute with lower memory usage and invariant to view-point change, blur change, brightness change, and JPEG compression.

Abstract:

The framers of the Curriculum and Evaluation Standards for School Mathematics (NCTM 1989) call for a radical “design change” in all aspects of mathematics education. They believe that “evaluation is a tool for implementing the Standards and effecting change systematically” (p. 189). They warn, however, that “without changes in how mathematics is assessed, the vision of the mathematics curriculum described in the standards will not be implemented in classrooms, regardless of how texts or local curricula change” (p. 252).

Abstract:

A recursive descent tree traversal algorithm is presented to find the point correspondences between two views. Given two sets of noisy 3-D feature points on multiple rigid objects at two time-sequential views, the points at the first view are constructed as a graph and then another graph is derived from those feature points at the second view so that a maximal matching point and minimum matching error is obtained. The correspondence of the vertices is then found. The algorithm can also he used when the number of points at two views are different. Therefore, after matching, the occluded points at either view or both views can be identified. The computation time of the proposed algorithm is large when the number of feature points is large. A data set splitting strategy for such cases, which can significantly reduce the computation time, is presented. Another algorithm presented is one in which motion parameters are estimated from a matched subgraph and are then used to guide the matching for the rest of the nodes. Computer simulations are performed to show the efficiency and accuracy of the algorithm.

Abstract:

Three-dimensional (3D) shape recognition has drawn much research attention in the field of computer vision. The advances of deep learning encourage various deep models for 3D feature representation. For point cloud and multi-view data, two popular 3D data modalities, different models are proposed with remarkable performance. However the relation between point cloud and views has been rarely investigated. In this paper, we introduce Point-View Relation Network (PVRNet), an effective network designed to well fuse the view features and the point cloud feature with a proposed relation score module. More specifically, based on the relation score module, the point-single-view fusion feature is first extracted by fusing the point cloud feature and each single view feature with point-singe-view relation, then the pointmulti- view fusion feature is extracted by fusing the point cloud feature and the features of different number of views with point-multi-view relation. Finally, the point-single-view fusion feature and point-multi-view fusion feature are further combined together to achieve a unified representation for a 3D shape. Our proposed PVRNet has been evaluated on ModelNet40 dataset for 3D shape classification and retrieval. Experimental results indicate our model can achieve significant performance improvement compared with the state-of-the-art models.

Abstract:

Subject area Strategy, Emiratisation (national policy); human resources (recruitment, training and development, organizational culture and values) and marketing (branding, communication), tourism (destination image). Study level/applicability Undergraduate and Postgraduate Business and Management. Case overview This case highlights the strategy and initiatives taken by Etihad to attract Emirati employees (local nationals) to join the organization. Etihad Airways is the national airline of the United Arab Emirates (UAE), based in Abu Dhabi, the national capital. Since its inception in 2003, the airline has grown faster than any other in commercial aviation history; it currently flies to more than 60 destinations in Africa, Asia, Australia, Europe, the Middle East and North America. In the UAE, nationals or Emiratis comprise only 20 per cent of the overall population. According to the UAE 2021 Vision, the government's focus is on building the human capabilities on knowledge and innovation for Emiratis. This vision is reinforced in the Abu Dhabi Economic Vision 2030, which aims to boost national participation, encourage women (national women are on average more highly educated than the men) and decrease the education – market demand gap through training. Expected learning outcomes This case can be used to teach strategy from the point of view of government, human resources and marketing. From the government point of view parallels can be drawn to other nations whose government have focused on policies to create opportunities for and to encourage local employability. An example of a similar programme that was very successful is the “Bumiputra” programme created for indigenous Malaysians in 1971. In the area of human resource strategy, recruitment, training, inculcation of corporate values are some areas that can be reinforced. Form the point of view of marketing; the case can be used to discuss branding from the point of view of people, loyalty building (internal) and communication (internal and external). Destination branding and the role airlines play can also be a discussion point from the strategic point of view with some opportunity for macro-environmental analysis using the PESTLE model.

Abstract:

For the problem of 3D line reconstruction in binocular or multiple view stereo vision, when there are no corresponding points on the line, the method called Direction-then-Point (DtP) can be used, and if there are two pairs of corresponding points on the line, the method called Two Points 3D coordinates (TPS) can be used. However, when there is only one pair of corresponding points on the line, can we get the better accuracy than DtP for 3D line reconstruction? In this paper, a linear and more accurate method called Point-then-Direction (PtD) is proposed. First, we used the intersection method to obtain the 3D point’s coordinate from its corresponding image points. Then, we used this point as a position on the line to calculate the direction of the line by minimizing the image angle residual. PtD is also suitable for multiple camera systems. The simulation results demonstrate that PtD increases the accuracy of both the direction and the position of the 3D line compared to DtP. At the same time, PtD achieves a better result in direction of the 3D line than TPS, but has a lower accuracy in the position of 3D lines than TPS.

Abstract:

Efficient and precise three-dimensional (3D) measurement is an important issue in the field of machine vision. In this paper, a measurement method for indoor key points is proposed with structured lights and omnidirectional vision system and the system can achieve the wide field of view and accurate results. In this paper, the process of obtaining indoor key points is as follows: Firstly, through the analysis of the system imaging model, an omnidirectional vision system based on structured light is constructed. Secondly, the full convolution neural network is used to estimate the scene for the dataset. Then, according to the geometric relationship between the scenery point and its reference point in structured light, for obtaining the 3D coordinates of the unstructured light point is presented. Finally, combining the full convolution network model and the structured light 3D vision model, the 3D mathematical representation of the key points of the indoor scene frame is completed. The experimental results proved that the proposed method can accurately reconstruct indoor scenes, and the measurement error is about 2%.

Abstract:

Abstract To reconstruct the points in three dimensional space, we need at least two images. In this paper we compared two different methods: the first uses only two images, the second one uses three. During the research we measured how camera resolution, camera angles and camera distances influence the number of reconstructed points and the dispersion of them. The paper presents that using the two-view method, we can reconstruct significantly more points than using the other one, but the dispersion of points is smaller if we use the three-view method. Taking into consideration the different camera settings, we can say that both the two- and three-view method behaves the same, and the best parameters are also the same for both methods.

Abstract:

NCTM's development of the Curriculum and Evaluation Standards for School Mathematics (NCTM 1989) and the recent companion document, Professional Standards for Teaching Mathematics (NCTM 1991), is an extraordinary achievement. At a time when many agree that we urgently need change in mathematics education, these sets of standards project an exciting vision of what mathematics learning can be and how all students can develop “mathematical power.” They establish a broad framework to guide reform efforts and challenge everyone interested in the quality of school mathematics programs to work collaboratively to use them as a basis for change. How will we meet this challenge? The Editorial Panel believes that translating that vision into reality at the elementary school level will be possible only if elementary school teachers are involved in taking leadership roles as agents of change.

Full text

Abstract:

A joint and unified vision of stochastic diffusion models associated with the family of hyperbolastic curves is presented. The motivation behind this approach stems from the fact that all hyperbolastic curves verify a linear differential equation of the Malthusian type. By virtue of this, and by adding a multiplicative noise to said ordinary differential equation, a diffusion process may be associated with each curve whose mean function is said curve. The inference in the resulting processes is presented jointly, as well as the strategies developed to obtain the initial solutions necessary for the numerical resolution of the system of equations resulting from the application of the maximum likelihood method. The common perspective presented is especially useful for the implementation of the necessary procedures for fitting the models to real data. Some examples based on simulated data support the suitability of the development described in the present paper.

Abstract:

Implementing the NCTM's curriculum and evaluation standards will require a change in the beliefs of many mathematics teachers and widespread acceptance of a fundamental premise of the Standards: that “appropriate calculators should be available to all students at all times” (Commission on Standards for School Mathematics of the NCTM 1989. 8). It will require widespread acceptance of the use of calculators in testing, for as the Standards observes, “until tests provide for the appropriate use of calculators, many teachers will continue to prohibit their use in the classroom. Without changes in how mathematics is assessed, the vision of the mathematics curriculum described in the standards will not be implemented in classrooms, regardless of how texts or local curricula change.”

Abstract:

Multisensor systems can overcome the limitation of measurement range of single-sensor systems, but often require complex calibration and data fusion. In this study, a three-dimensional (3D) measurement method of four-view stereo vision based on Gaussian process (GP) regression is proposed. Two sets of point cloud data of the measured object are obtained by gray-code phase-shifting technique. On the basis of the characteristics of the measured object, specific composite kernel functions are designed to obtain the initial GP model. In view of the difference of noise in each group of point cloud data, the weight idea is introduced to optimize the GP model, which is the data fusion based on Bayesian inference method for point cloud data. The proposed method does not require strict hardware constraints. Simulations for the curve and the high-order surface and experiments of complex 3D objects have been designed to compare the reconstructing accuracy of the proposed method and the traditional methods. The results show that the proposed method is superior to the traditional methods in measurement accuracy and reconstruction effect.

Abstract:

This paper presents an automatic three-dimensional reconstruction method based on multi-view stereo vision for the Mogao Grottoes. 3D digitization technique has been used in cultural heritage conservation and replication over the past decade, especially the methods based on binocular stereo vision. However, mismatched points are inevitable in traditional binocular stereo matching due to repeatable or similar features of binocular images. In order to reduce the probability of mismatching greatly and improve the measure precision, a portable four-camera photographic measurement system is used for 3D modelling of a scene. Four cameras of the measurement system form six binocular systems with baselines of different lengths to add extra matching constraints and offer multiple measurements. Matching error based on epipolar constraint is introduced to remove the mismatched points. Finally, an accurate point cloud can be generated by multi-images matching and sub-pixel interpolation. Delaunay triangulation and texture mapping are performed to obtain the 3D model of a scene. The method has been tested on 3D reconstruction several scenes of the Mogao Grottoes and good results verify the effectiveness of the method.

Abstract:

This paper proposes a fast colour-based object recognition and localization for soccer robots. The traditional HSL colour model is modified for better colour segmentation and edge detection in a colour coded environment. The object recognition is based on only the edge pixels to speed up the computation. The edge pixels are detected by intelligently scanning a small part of whole image pixels which is distributed over the image. A fast method for line and circle centre detection is also discussed. For object localization, 26 key points are defined on the soccer field. While two or more key points can be seen from the robot camera view, the three rotation angles are adjusted to achieve a precise localization of robots and other objects. If no key point is detected, the robot position is estimated according to the history of robot movement and the feedback from the motors and sensors. The experiments on NAO and RoboErectus teen-size humanoid robots show that the proposed vision system is robust and accurate under different lighting conditions and can effectively and precisely locate robots and other objects.

Abstract:

This essay develops a new approach to print narratives about theatregoing during the Victorian and Edwardian periods. Immensely popular with contemporary readers, theatrical memoirs and diaries have been a boon to theatre historians of the nineteenth and early twentieth centuries; but these texts have more often been studied in spite of their subjective perspectives than because of them. Building on work in theatre historiography and audience studies, this essay seeks to transform the spectator’s discursive acts of shaping, framing, and stressing from an obstacle into an opportunity. In order to resituate historical spectator narratives in a wider narrative context, I read diaries and essays by Henry Crabb Robinson and Lady Maud Tree in conversation with Charlotte Brontë’s fictional scenes of spectatorship in Villette. This intertextual approach, I suggest, yields a more complete understanding of how different points of view facilitated claims about performance. In particular, I explore how gender affected point of view. While male reviewers and diarists often employ a disinterested narrative persona that de-emphasises their own bodies, I argue that many actress autobiographies craft an alternative form of narrative authority that makes use of the limitations of embodiment – qualities like immobility, bodily sensation, and circumscribed vision.

Abstract:

The available guide tools of the orientation and mobility for a blind are the cane, guide dog and electronic guide devices. A cane is easy to detect the hindrance that is in front of the user but not for the hindrance above the user waist. That's why a cane user of a blind sometimes will be hit by the upper hindrance. Guide dog is a very powerful mobility guider but expensive and the training and living care for the dogs are difficult. Hence, guide dog is not popular in many countries. The electronic devices for blind guide tools such as laser cane; sonic glasses, sonic guide etc. can only detect a single point at a time and not for a whole view. In our system, a machine vision blind guide system is proposed. A CCD grabbed the image of front view and divided the image into nine blocks. Each block is calculated to get the distance message, which is multipoint data to guide the blind by the converted voice signal.

Abstract:

Finding a parallel architecture adapted to a given class of algorithms is a central problem for architects. This paper presents a methodology to realize it, and provides an illustration using image analysis. First, we show a set of common basic operations that can be used to solve most image analysis problems. Then these movements are translated to fit some natural communications in a given architecture. The considered data movements (global operations on connected pixel sets) can express a large class of algorithms. Their implementation on exemplary massively parallel architectures (arrays, hypercubes, pyramids) is discussed.

Abstract:

Vision based localization is widely investigated for the autonomous navigation and robotics. One of the basic steps of vision based localization is the extraction of interest points in images that are captured by the embedded camera. In this paper, SIFT and SURF extractors were chosen to evaluate their performance in localization. Four street view image sequences captured by a mobile mapping system, were used for the evaluation and both SIFT and SURF were tested on different image scales. Besides, the impact of the interest point distribution was also studied. We evaluated the performances from for aspects: repeatability, precision, accuracy and runtime. The local bundle adjustment method was applied to refine the pose parameters and the 3D coordinates of tie points. According to the results of our experiments, SIFT was more reliable than SURF. Apart from this, both the accuracy and the efficiency of localization can be improved if the distribution of feature points are well constrained for SIFT.

Abstract:

A portable three-dimensional vision coordinate measuring system is proposed in this paper. It consists of a light pen, a CCD camera and a laptop computer. The light pen is a hand-held probe with three point light sources using LEDs and a spherical touch stylus arranged in one line. The CCD camera takes the image of LEDs on the light pen and the 3D coordinates of measured point at the center of touch stylus are obtained by computing the positions of LEDs in the image when the probe contacts the object surface. The equations of the vision measurement system are derived by using perspective of three collinear points and spatial analytic geometry. The measuring device can be set up easily on an industrial site and the measurement is convenient. The object surface can be simple, complex, or hidden from the view of camera. The effectiveness of the mathematical model and validity of the measuring system are confirmed by experiments.

Abstract:

Se realiza un análisis de la visión étnico-cultural en la obra narrativa y ensayística de Yolanda Oreamuno. Se centra en la percepción, valoración y representación que Oreamuno lleva a cabo sobre indígenas y afrodescendientes. Esta revisión exhaustiva de su obra lleva a concluir que su visión está sesgada y no es ajena al punto de vista predominante en los escritores de su misma generación: todos marcados por una matriz ideológica racista. El feminismo del que es abanderada Oreamuno no se sostiene cuando se refiere a mujeres indígenas y negras: contra ellas no solo es clasista y racista, sino también sexista.We analyze the ethnocultural view present in Yolanda Oreamuno’s narrative and essayistic work, and focus on the perception, assessment and representation of Oreamuno concerning indigenous and afro-descendant peoples. This thorough review of her work makes is possible to conclude that her vision is biased, and akin to the predominant point of view in writers of her same generation, all of whom influenced by a racist ideological matrix. The feminism of which Oreamuno is considered a flag bearer is not upheld regarding indigenous or black women, where it becomes not only classist and racist, but also sexist.

Abstract:

Pavement macrotexture contributes greatly to road surface friction, which in turn plays a vital role in reducing road accidents. Conventional methods for macrotexture measurement are either expensive, time-consuming, or of poor repeatability. Based on multi-view smartphone images collected in situ, this paper develops and evaluates an affordable and convenient alternative approach for pavement macrotexture measurement. Photogrammetric computer vision techniques are first applied to create high resolution point clouds of the pavement. Analytics are then developed to determine the macrotexture metric: mean profile depth by using the image-based point clouds. Experiments are carried out with 790 images over 25 spots on three state routes and six spots at an Indiana Department of Transportation test site. We demonstrate multi-view smartphone images can yield results comparable to the ones from the conventional laser texture scanner. It is expected that the developed approach can be adopted for large scale operational uses.

Abstract:

Nowadays, with the development of the urban areas, the automatic reconstruction of the buildings, as an important objects of the city complex structures, became a challenging topic in computer vision and photogrammetric researches. In this paper, the capability of multi-view Unmanned Aerial Vehicles (UAVs) images is examined to provide a 3D model of complex building façades using an efficient image-based modelling workflow. The main steps of this work include: pose estimation, point cloud generation, and 3D modelling. After improving the initial values of interior and exterior parameters at first step, an efficient image matching technique such as Semi Global Matching (SGM) is applied on UAV images and a dense point cloud is generated. Then, a mesh model of points is calculated using Delaunay 2.5D triangulation and refined to obtain an accurate model of building. Finally, a texture is assigned to mesh in order to create a realistic 3D model. The resulting model has provided enough details of building based on visual assessment.
