This book was released on 1996 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study presents a three-dimensional computer vision inspection and measurement system, in which stereo vision and neural networks are incorporated measurement tasks. The main objective of this proposed research is to automatically measure an industrial part in three-dimensions by using parallel stereo vision. Two major problems, stereo matching and measurement error correction, are solved. Matching conjugate features is a significant problem in using a stereo vision system. A feature-based matching method is proposed to solve this problem. The proposed algorithm includes: selecting significant feature points, matching conjugate feature points by a "0-1" integer programming problem, and removing false targets according to suggested rules. An energy function is created and minimized by using an asynchronous Hopfield neural network with a derived activation rule. The disparities of conjugate feature points are the derived results. A triangulation-based camera calibration model is used to derive the focal length and correct the X-Y ratio of the cameras. An operational process is proposed to collect the data and derive the focal length. Boundary representation is used to identify and decompose the feature of interest, and then initial measurements are made. A neural network based error correction procedure is proposed to solve the measurement error correction problem. By means of a backpropagation neural network, the mapping of the influential factors and correction ratios is established. The derived correction ratios are used to correct the initial measurements. Three processes--training, testing and operational procedures--are proposed to facilitate the error correction process. A comparison with Nascrabadi's approach shows that the proposed stereo matching algorithm has superior matching performance in speed, storage, and correctness. The derived initial measurements demonstrate that the focal lengths are accurately estimated by the proposed calibration method. Also, the proposed error correction model further improves the accuracy and precision of the measurements.

Download or read book View Synthesis Using Stereo Vision written by Daniel Scharstein and published by Springer. This book was released on 2003-06-29 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Image-based rendering, as an area of overlap between computer graphics and computer vision, uses computer vision techniques to aid in sythesizing new views of scenes. Image-based rendering methods are having a substantial impact on the field of computer graphics, and also play an important role in the related field of multimedia systems, for applications such as teleconferencing, remote instruction and surgery, virtual reality and entertainment. The book develops a novel way of formalizing the view synthesis problem under the full perspective model, yielding a clean, linear warping equation. It shows new techniques for dealing with visibility issues such as partial occlusion and "holes". Furthermore, the author thoroughly re-evaluates the requirements that view synthesis places on stereo algorithms and introduces two novel stereo algorithms specifically tailored to the application of view synthesis.

Book excerpt: Today, human factors and ergonomics professionals worldwide contribute to the design and evaluation of tasks, jobs, products, environments, and systems in order to make them compatible with the needs, abilities, and limitations of people. By understanding anthropometry, professionals can ensure that our home and working environments are comfortable and designed with the human in mind. This book aims to show how an understanding of anthropometrics can influence workspace design, ergonomics in the office, ergonomics in the home, and health and safety at work. This book discusses the measurement of the human body and human variability. Anthropometry may seem to be relatively simple but the reality is that it focuses on very sophisticated aspects of how to make the products tailor-made to suit specific requirements. As a study, it is useful for a variety of purposes such as workspace design, ergonomics in the office, ergonomics in the home, and health and safety at work. These eleven chapters investigate anthropometrics and bridge the gap between theory and practice. Each chapter is supported by tables, charts, and illustrations, and a wide list of bibliographic references. The reader will develop new insights into the principles and practice of anthropometrics with this book bringing the topic right up to date. Anthropometry: Human Body Measurements and How to Use Them will be of interest to students, graduates, teachers, researchers, and general workers in industrial design, ergonomics, rehabilitation, safety, and health.

Download or read book Perceiving in Depth, Volume 2: Stereoscopic Vision written by Ian P. Howard and published by Oxford University Press. This book was released on 2012-01-27 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 2 addresses stereoscopic vision in cats and primates, including humans. It begins with an account of the physiology of stereoscopic mechanisms. It then deals with binocular rivalry, binocular summation, binocular masking, and the interocular transfer of visual effects, such as the motion aftereffect and visual learning. The geometry of the region in binocular space that creates fused images (the horopter) is discussed in some detail. Objects outside the horopter produce images with binocular disparities that are used for stereoscopic vision. Two chapters provide accounts of mechanisms that bring the images into binocular register and of stimulus tokens that are used to detect binocular disparities. Another chapter discusses cyclopean effects, such as cyclopean illusions, cyclopean motion, and binocular direction that are seen only with binocular vision. Stereoacuity is the smallest depth interval that can be detected. Methods of measuring stereoacuity and factors that influence it are discussed. Two chapters deal with the various types of binocular disparity and the role of each type in stereoscopic vision. Another chapter deals with visual effects, such as figure perception, motion perception, and whiteness perception that are affected by the relative distances of stimuli. The spatiotemporal aspects of stereoscopic vision, including the Pulfrich stereomotion effect are reviewed. The volume ends with an account of techniques used to create stereoscopic displays and of the applications of stereoscopy.

This book was released on 2015-10-19 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer Vision and Pattern Recognition (CVPR) together play an important role in the processes involved in environmental informatics due to their pervasive, non-destructive, effective, and efficient natures. As a result, CVPR has made significant contributions to the field of environmental informatics by enabling multi-modal data fusion and feature extraction, supporting fast and reliable object detection and classification, and mining the intrinsic relationship between different aspects of environmental data. Computer Vision and Pattern Recognition in Environmental Informatics describes a number of methods and tools for image interpretation and analysis, which enables observation, modelling, and understanding of environmental targets. In addition to case studies on monitoring and modeling plant, soil, insect, and aquatic animals, this publication includes discussions on innovative new ideas related to environmental monitoring, automatic fish segmentation and recognition, real-time motion tracking systems, sparse coding and decision fusion, and cell phone image-based classification and provides useful references for professionals, researchers, engineers, and students with various backgrounds within a multitude of communities.
