Abstract:
In this paper, a novel feature-based real-time visual Simultaneous localization and mapping (SLAM) system is proposed. This system generates colored 3-D reconstruction models and 3-D estimated trajectory using a Kinect style camera. Microsoft Kinect, a low priced 3-D camera, is the only sensor we use in our experiment. Kinect style sensors give RGB-D (red-green-blue depth) data which contains 2D image and per-pixel depth information. ORB (Oriented FAST and Rotated BRIEF) is the algorithm used to extract image features for speed up the whole system. Our system can be used to generate 3-D detailed reconstruction models. Furthermore, an estimated 3D trajectory of the sensor is given in this paper. The results of the experiments demonstrate that our system performs robustly and effectively in both getting detailed 3D models and mapping camera trajectory.

Abstract:
AbstractIn time-based visual selection, task-irrelevant, old stimuli can be inhibited in order to allow the selective processing of new stimuli that appear at a later point in time (the preview benefit; Watson & Humphreys, 1997). The current study investigated if illusory and non-illusory perceptual groups influence the ability to inhibit old and prioritize new stimuli in time-based visual selection. Experiment 1 showed that with Kanizsa-type illusory stimuli, a preview benefit occurred only when displays contained a small number of items. Experiment 2 demonstrated that a set of Kanizsa-type illusory stimuli could be selectively searched amongst a set of non-illusory distractors with no additional preview benefit obtained by separating the two sets of stimuli in time. Experiment 3 showed that, similarly to Experiment 1, non-illusory perceptual groups also produced a preview benefit only for a small number of number of distractors. Experiment 4 demonstrated that local changes to perceptually grouped old items eliminated the preview benefit. The results indicate that the preview benefit is reduced in capacity when applied to complex stimuli that require perceptual grouping, regardless of whether the grouped elements elicit illusory contours. Further, inhibition is applied at the level of grouped objects, rather than to the individual elements making up those groups. The findings are discussed in terms of capacity limits in the inhibition of old distractor stimuli when they consist of perceptual groups, the attentional requirements of forming perceptual groups and the mechanisms and efficiency of time-based visual selection.

Abstract:
Physiological theories indicate that the deepest impression for time series data with respect to the human visual system is its extreme value. Based on this principle, by researching the strategies of extreme-point-based hierarchy segmentation, the hierarchy-segmentation-based data extraction method for time series, and the ideas of locality outlier, a novel outlier detection model and method for time series are proposed. The presented algorithm intuitively labels an outlier factor to each subsequence in time series such that the visual outlier detection gets relatively direct. The experimental results demonstrate the average advantage of the developed method over the compared methods and the efficient data reduction capability for time series, which indicates the promising performance of the proposed method and its practical application value.

Full text
Abstract:
There are three main results in this dissertation. The first result is the construction of an abstract visual space for rational numbers mod1, based on the visual primitives, colour, and rational radial direction. Mathematics is performed in this visual notation by defining increasingly refined visual objects from these primitives. In particular, the existence of the Farey tree enumeration of rational numbers mod1 is identified in the texture of a two-dimensional animation. ¶ The second result is a new enumeration of the rational numbers mod1, obtained, and expressed, in abstract visual space, as the visual object coset waves of coset fans on the torus. Its geometry is shown to encode a countably infinite tree structure, whose branches are cosets, nZ+m, where n, m (and k) are integers. These cosets are in geometrical 1-1 correspondence with sequences kn+m, (of denominators) of rational numbers, and with visual subobjects of the torus called coset fans. ¶ The third result is an enumeration in time of the visual hierarchy of the discrete buds of the Mandelbrot boundary by coset waves of coset fans. It is constructed by embedding the circular Farey tree geometrically into the empty internal region of the Mandelbrot set. In particular, coset fans attached to points of the (internal) binary tree index countably infinite sequences of buds on the (external) Mandelbrot boundary.

Full text
Abstract:
The biological and behavioural importance of the face has led to the proposition of several mechanisms dedicated to highly efficient specialized processing (e.g., M.H. Johnston, 2005). This is reflected in the attentional properties attributed to facial stimuli, especially when they contain affective information (e.g., R. Palermo & G. Rhodes, 2007). This thesis examines those attentional properties via a modified version of the visual search paradigm (i.e. the preview search task; D.G. Watson & G.W. Humphreys, 1997), which proposes that observers can intentionally suppress items seen prior to a full search array, for effective search performance (i.e. the preview benefit; D.G.Watson & G.W. Humphreys, 1997, 1998). The findings from this thesis show that it is possible to deprioritize previewed facial stimuli from search, although only a partial preview benefit was shown. Emotional valence of previewed faces had little impact on this effect, even when preview duration was extended from 1000-3000ms. However, when duration was reduced to 250-750 ms, negatively valenced faces were more difficult to suppress than positively valenced faces. In addition, when previewed faces changed expression concurrently with the onset of the full search array, the preview benefit was abolished, irrespective of the direction of the expression change (i.e. neutral to positive, or neutral to negative). A search advantage for negative face targets was demonstrated throughout all of the investigations in this thesis. These findings are consistent with previous work establishing preferential detection of, and selectively impaired disengagement from, negative faces (e.g., J.D. Eastwood, D. Smilek, & P.M. Merikle, 2001; E.Fox, R. Russo, R.J.Bowles, & K. Dutton, 2001). However, they also suggest the sensitivity of the visual marking mechanism to ecological considerations (such as the nature of the stimulus), and the overall relevance of emotional face stimuli to the visual system.

Abstract:
Attention plays an integral role in healthy cognitive functioning, and failures of attention can lead to unfavourable and dangerous consequences. As such, comprehending the nature of attentional mechanisms is of fundamental theoretical and practical importance. One way in which humans can attentionally prioritise new information is through top-down inhibition of old distractors, known as the preview benefit (Watson & Humphreys, 1997). In the preview benefit, time is used to efficiently guide visual selection in space. Given that this ability is based on limited resources, its deployment in everyday life may be hindered by a multitude of factors. This thesis will explore the endogenous and exogenous factors that can facilitate or constrain the preview benefit, and determine its developmental trajectory. Understanding the nature of this mechanism (endogenous and exogenous factors) in adults can elucidate the contexts in which visual selection can efficiently filter old distractors. In turn, a developmental perspective can unravel the hidden aspects of this ability and inform when children are endowed to use temporal information for efficient attentional selection. Chapter 1 introduces the theoretical problems and topics of attentional research in adults and children. Chapter 2 addresses the question of endogenous control of top-down inhibition in time-based visual selection – when can top-down inhibition be controlled by the observer? Chapter 3 examines the exogenous influence of complex stimuli on time-based visual selection. Chapters 4 and 5 focus on the development of time-based visual selection for stationary and moving stimuli, respectively, in children aged 6 to 12 years. These chapters also examine the relative association of the efficiency of the preview benefit with the development of executive functions across different age-groups. Overall, the findings suggest that there exist remarkable endogenous and exogenous constraints in how time guides selection. This may account for why in certain contexts, attentional selection can fail to be efficient. Moreover, time-based visual selection shows striking quantitative and qualitative changes over developmental time, and most importantly, children have a long developmental trajectory in learning to ignore moving items. Unlike children, adults’ time-based visual selection is coupled with individual differences in executive functions, highlighting an acquired functional connection. The findings are discussed in terms of their theoretical implications for time-based visual selection, the development of children’s attentional control for distractors, and impact routes for educational and clinical practice, and policy makers.

Abstract:
The purpose of this thesis is to show the application of modern digital techniques to produce a high speed computational system that has the capability of producing a faster than real-time model for the visual systems associated with flight simulator systems. A distributed/multiprocessing system was chosen due to the increased reliability, flexibility and throughput of the computational process. The system also has the advantage of providing increased modularity and ease of expansion. This research is firstly concerned with the development of a high resolution graphics system (providing a 1024 by 1024 point screen resolution), and the techniques for the production of moving visual scenes observed by a pilot when flying over a region of terrain in a flight simulator. In particular, this work is concerned with the real-time simulation of the aerodynamics of the aircraft and considers the problems of designing and accessing a data base which represents a model of the terrain. There are three major design considerations for the real-time CGI (Computer Generated Imagery) system of the type required. The first is to ensure that all processing for each picture frame is performed within a specified time limit. Secondly, the picture must have a realistic appearance and requires realism functions to be performed in real-time. The third design consideration is the cost.

Abstract:
This dissertation discusses vision-based static obstacle avoidance for a fleet of nonholonomic robots tasked to arrive at a final destination simultaneously. Path generation for each vehicle is computed using a single polynomial function that incorporates the vehicle constraints on velocity and acceleration and satisfies boundary conditions by construction. Furthermore, the arrival criterion and a preliminary obstacle avoidance scheme is incorporated into the path generation. Each robot is equipped with an inertial measurement unit that provides measurements of the vehicleâ s position and velocity, and a monocular camera that detects obstacles. The obstacle avoidance algorithm deforms the vehicleâ s original path around at most one obstacle per vehicle in a direction that minimizes an obstacle avoidance potential function. Deconfliction of the vehicles during obstacle avoidance is achieved by imposing a separation condition at the path generation level. Two estimation schemes are applied to estimate the unknown obstacle parameters. The first is an existing method known in the literature as Identifier-Based Observer and the second is a recently-developed fast estimator. It is shown that the performance of the fast estimator and its effect on the obstacle avoidance algorithm can be arbitrarily improved by the appropriate choice of parameters as compared to the Identifier-Based Observer method. Coordination in time of all vehicles is completed in an outer loop which adjusts the desired velocity profile of each vehicle in order to meet the simultaneous arrival constraints. Simulation results illustrate the theoretical findings.

Abstract:
This chapter introduces the main ideas about the use of quality-adjusted life years (QALYs) in the evaluation of health policies. It starts by explaining the theoretical underpinnings of the QALY model understood as individual utilities. Afterward, it reviews the empirical evidence about the descriptive validity of the main assumptions supporting the model. Then, it explains the main preference elicitation techniques (visual analog scale, time trade-off, and standard gamble). It also shows the practical psychological problems faced by these techniques, such as the existence of context-dependent preferences. The chapter ends by explaining how QALYs are used in priority setting, in particular, the rules governing resources allocation decisions using QALYs, the ethical implications of these rules, and the relationship between cost-benefit analysis and cost-effectiveness analysis.

This book aims to explore the aspects of visuality in Greek and Roman culture, comprising the visual appearance of images as well as the reality of the social world. The face-to-face societies of ancient Greece and Rome were to a high degree based on civic presence and direct, immediate social interaction in which visual appearance and experience of beings and things was of paramount importance. The six chapters of the book are dedicated to action in space, memory over time, the appearance of the person, conceptualization of reality, and, finally, presentification and decor as fundamental categories of art in social practice.

Abstract:
Stress echocardiography has evolved over the last 30 years but image interpretation remains subjective and burdened by the operator’s experience. The objective operator-independent assessment of myocardial ischaemia during stress echocardiography remains a technological challenge. Still, adequate quality of two-dimensional images remains a prerequisite to successful quantitative analysis, even using Doppler and non-Doppler based techniques. No new technology has proved to have a higher diagnostic accuracy than conventional visual wall motion analysis. Tissue Doppler imaging and derivatives may reduce inter-observer variability, but still require a dedicated learning curve and special expertise. The development of contrast media in echocardiography has been slow. In the past decade, transpulmonary contrast agents have become commercially available for clinical use. The approved indication for the use of contrast echocardiography currently lies in improving endocardial border delineation in patients in whom adequate imaging is difficult or suboptimal. Real-time three-dimensional echocardiography is potentially useful but limited by low spatial and temporal resolution. It is possible that these technologies may serve as an adjunct to expert visual assessment of wall motion. At present, these quantitative methods require further validation and simplification of analysis techniques.

Abstract:
The Art of Cinematic Storytelling: A Visual Guide to Planning Shots, Cuts, and Transitions is a practical introduction to the design of shots, cuts, and transitions for film, video, television, animation, and game design. The author-illustrator is a storyboard artist who has worked with and learned from over 200 professional directors and cinematographers. This book’s clear and concise explanations and vivid examples demystify the visual design choices that are fundamental to directing and editing. Hundreds of illustrations and diagrams support the text. The primary emphasis is on blocking actors and positioning the camera for mood, meaning, and continuity editing. This book delves deeply into controlling the audience’s understanding and perception of time and space; designing in-camera time transitions; compressing and expanding time; composing creative shots for cinematic storytelling; choosing between objective and subjective storytelling; motivating camera moves; choosing lenses; using screen geography and film grammar for clarity; planning shots with continuity editing in mind; knowing how and when to cut; beginning and ending scenes; and using storyboards for planning and communication. Several chapters are devoted to how to block and shoot action involving travel, pursuits, searches, dialogue, groups, and driving. While the approach is based largely on well-established techniques of cinematography and continuity editing, attention is also given to jump cuts, tableau shots, and unconventional framing. The topics are covered thoroughly and systematically, and this book serves both as an introductory text and as a reference work for more advanced students of film.

The anniversary years of the composer Gustav Mahler (150 years of his birth in 2010, 100 years of his death in 2011) took place in the age of digital media, whose technological possibilities afforded strikingly diverse opportunities to mark the occasion. Various experimental sound and video artists, produced audiovisual translations and interpretations of the composer’s music at this time, including Danish composer Henrik Marstal with VJ Dark Matters, and Austrian experimental composer Fennesz with Berlin-based video artist Lillevan. Building on a tradition which had begun in the 1990s, this repertoire is examined here from the theoretical and historical perspectives of “visual music” and intermediality.

Abstract:
Recent advances in visual sensing technology have gained much attention in the field of bridge inspection and management. Coupled with advanced robotic systems, state-of-the-art visual sensors can be used to obtain accurate documentation of bridges without the need for any special equipment or traffic closure. The captured visual sensor data can be post-processed to gather meaningful information for the bridge structures and hence to support bridge inspection and management. However, state-of-the-practice data postprocessing approaches require substantial manual operations, which can be time-consuming and expensive. The main objective of this study is to develop methods and algorithms to automate the post-processing of the visual sensor data towards the extraction of three main categories of information: 1) object information such as object identity, shapes, and spatial relationships - a novel heuristic-based method is proposed to automate the detection and recognition of main structural elements of steel girder bridges in both terrestrial and unmanned aerial vehicle (UAV)-based laser scanning data. Domain knowledge on the geometric and topological constraints of the structural elements is modeled and utilized as heuristics to guide the search as well as to reject erroneous detection results. 2) structural damage information, such as damage locations and quantities - to support the assessment of damage associated with small deformations, an advanced crack assessment method is proposed to enable automated detection and quantification of concrete cracks in critical structural elements based on UAV-based visual sensor data. In terms of damage associated with large deformations, based on the surface normal-based method proposed in Guldur et al. (2014), a new algorithm is developed to enhance the robustness of damage assessment for structural elements with curved surfaces. 3) three-dimensional volumetric models - the object information extracted from the laser scanning data is exploited to create a complete geometric representation for each structural element. In addition, mesh generation algorithms are developed to automatically convert the geometric representations into conformal all-hexahedron finite element meshes, which can be finally assembled to create a finite element model of the entire bridge. To validate the effectiveness of the developed methods and algorithms, several field data collections have been conducted to collect both the visual sensor data and the physical measurements from experimental specimens and in-service bridges. The data were collected using both terrestrial laser scanners combined with images, and laser scanners and cameras mounted to unmanned aerial vehicles.

Abstract:
Mobile wallets replicate physical wallets on a mobile device, in which users can store different payment instruments (e.g., cards, transfers) to make mobile payments. As the mobile wallet is adopted, a mobile payment scheme emerges, with its users as elements in a network of transfers. In this article, I study the mobile payment scheme of Movii— the first fintech firm in Colombia operating under a financial non-banking license for electronic deposits and payments. Based on a unique dataset of bilateral transfers between Movii’s mobile wallet users, I build, visualize and analyze Movii’s network, daily from November 18, 2017, to November 25, 2020. Besides the anticipated increase in the number of users and the value of transfers, the visual and quantitative complexity of the network of transfers increases over time. This increase in complexity is likely to be linked to the adoption of Movii’s mobile wallet, which results in users finding new ways to use mobile payments beyond person-to-person transfers, including person-to-business and business-to-business. Also, results suggest the Covid-19 pandemic accelerated the evolution of Movii’s mobile payments scheme.

Abstract:
The article investigates functional techniques of extralinguistic expression in multimedia texts; the effectiveness of figurative expressions as a reaction to modern events in Ukraine and their influence on the formation of public opinion is shown. Publications of journalists, broadcasts of media resonators, experts, public figures, politicians, readers are analyzed. The language of the media plays a key role in shaping the worldview of the young political elite in the first place. The essence of each statement is a focused thought that reacts to events in the world or in one’s own country. The most popular platform for mass information and social interaction is, first of all, network journalism, which is characterized by mobility and unlimited time and space. Authors have complete freedom to express their views in direct language, including their own word formation. Phonetic, lexical, phraseological and stylistic means of speech create expression of the text. A figurative word, a good aphorism or proverb, a paraphrased expression, etc. enhance the effectiveness of a multimedia text. This is especially important for headlines that simultaneously inform and influence the views of millions of readers. Given the wide range of issues raised by the Internet as a medium, research in this area is interdisciplinary. The science of information, combining language and social communication, is at the forefront of global interactions. The Internet is an effective source of knowledge and a forum for free thought. Nonlinear texts (hypertexts) – «branching texts or texts that perform actions on request», multimedia texts change the principles of information collection, storage and dissemination, involving billions of readers in the discussion of global issues. Mastering the word is not an easy task if the author of the publication is not well-read, is not deep in the topic, does not know the psychology of the audience for which he writes. Therefore, the study of media broadcasting is an important component of the professional training of future journalists. The functions of the language of the media require the authors to make the right statements and convincing arguments in the text. Journalism education is not only knowledge of imperative and dispositive norms, but also apodictic ones. In practice, this means that there are rules in media creativity that are based on logical necessity. Apodicticity is the first sign of impressive language on the platform of print or electronic media. Social expression is a combination of creative abilities and linguistic competencies that a journalist realizes in his activity. Creative self-expression is realized in a set of many important factors in the media: the choice of topic, convincing arguments, logical presentation of ideas and deep philological education. Linguistic art, in contrast to painting, music, sculpture, accumulates all visual, auditory, tactile and empathic sensations in a universal sign – the word. The choice of the word for the reproduction of sensory and semantic meanings, its competent use in the appropriate context distinguishes the journalist-intellectual from other participants in forums, round tables, analytical or entertainment programs. Expressive speech in the media is a product of the intellect (ability to think) of all those who write on socio-political or economic topics. In the same plane with him – intelligence (awareness, prudence), the first sign of which (according to Ivan Ogienko) is a good knowledge of the language. Intellectual language is an important means of organizing a journalistic text. It, on the one hand, logically conveys the author’s thoughts, and on the other – encourages the reader to reflect and comprehend what is read. The richness of language is accumulated through continuous self-education and interesting communication. Studies of social expression as an important factor influencing the formation of public consciousness should open up new facets of rational and emotional media broadcasting; to trace physical and psychological reactions to communicative mimicry in the media. Speech mimicry as one of the methods of disguise is increasingly becoming a dangerous factor in manipulating the media. Mimicry is an unprincipled adaptation to the surrounding social conditions; one of the most famous examples of an animal characterized by mimicry (change of protective color and shape) is a chameleon. In a figurative sense, chameleons are called adaptive journalists. Observations show that mimicry in politics is to some extent a kind of game that, like every game, is always conditional and artificial.
