This book was released on 2012-12-06 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: An image or video sequence is a series of two-dimensional (2-D) images sequen tially ordered in time. Image sequences can be acquired, for instance, by video, motion picture, X-ray, or acoustic cameras, or they can be synthetically gen erated by sequentially ordering 2-D still images as in computer graphics and animation. The use of image sequences in areas such as entertainment, visual communications, multimedia, education, medicine, surveillance, remote control, and scientific research is constantly growing as the use of television and video systems are becoming more and more common. The boosted interest in digital video for both consumer and professional products, along with the availability of fast processors and memory at reasonable costs, has been a major driving force behind this growth. Before we elaborate on the two major terms that appear in the title of this book, namely motion analysis and image sequence processing, we like to place them in their proper contexts within the range of possible operations that involve image sequences. In this book, we choose to classify these operations into three major categories, namely (i) image sequence processing, (ii) image sequence analysis, and (iii) visualization. The interrelationship among these three categories is pictorially described in Figure 1 below in the form of an "image sequence triangle".

This book was released on 2012-12-06 with total page 759 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the NATO Advanced Study Institute on "Image Sequence Processing and Dynamic Scene Analysis" held 21 June - 2 July, 1982 in Hotel Maritim, Braunlage/Harz, Federal Republic of Germany. The organizing eommittee of the institute consists of T.S. Huang (Director), H.G. Musmann (Co Director), H.H. Nagel (Consultant), and C.E. Liedtke and W. Geuen (Local 'arrangement). This Institute was devoted to the rapidly emerging field of image sequence processing and dynamic scene analysis which has man! important applications in cluding target tracking, television bandwidth compression, highway traffic moni toring, and analysis of heart wall motion for medical diagnosis. The lectures and discussions in this Institute fell into three overlapping categories: Motion estimation; pattern recognition and artificial intelligence techniques in dynamic scene analysis; and, applications. 1) Motion estimation - One of the most important problems in image sequence analysis and dynamic scene analysis is displacement and motion estimation. For example, in interframe coding using temporal DPCM, displacement estimation and compensation can improve efficiency significantly. Also, estimated motion parameters can be powerful cues in target segmentation, detection, and classification. In this Institute, a number of recently developed techniques for displacement and motion estimation were discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Estimation of structure and six-degree-of-freedom motion of maneuvering objects through measurements of feature positions in long, multiple- camera image sequences is widely recognized to have broad industrial military and space applications, particularly in the control of autonomous systems. This report focuses on the case of maneuvering objectives thereby removing restrictive assumptions concerning the mode of translational and rotational motion which are commonly employed in many existing methods. Object maneuvers, being' smooth and time correlated, are modelled as first-order Gauss-Markov processes for both translational and rotational motion. In the literature, rotational motion is often parameterized with unit quaternions even though constrains on the quaternion norm are not easily enforced, roll-pitch-yaw parameterizations have been reported to be poorly behaved and have led to computationally demanding implementations, and results using the Euler angle- axis parameterization in recursive motion and structure estimation are not available. In this report, six-degree-of-freedom, nonlinear, approximate state estimation filters for quaternion, roll-pitch-yaw and angle-axis parameterizations are compared in terms of estimation performance for maneuvering object trajectories. Special consideration is given to the problem of imposing unit norm on the estimated quaternion since previously proposed methods led to filter instability, particularly in angular velocity estimation.

Available in PDF, EPUB and Kindle. Book excerpt: The processing of image sequences has a broad spectrum of important applica tions including target tracking, robot navigation, bandwidth compression of TV conferencing video signals, studying the motion of biological cells using microcinematography, cloud tracking, and highway traffic monitoring. Image sequence processing involves a large amount of data. However, because of the progress in computer, LSI, and VLSI technologies, we have now reached a stage when many useful processing tasks can be done in a reasonable amount of time. As a result, research and development activities in image sequence analysis have recently been growing at a rapid pace. An IEEE Computer Society Workshop on Computer Analysis of Time-Varying Imagery was held in Philadelphia, April 5-6, 1979. A related special issue of the IEEE Transactions on Pattern Anal ysis and Machine Intelligence was published in November 1980. The IEEE Com puter magazine has also published a special issue on the subject in 1981. The purpose of this book is to survey the field of image sequence analysis and to discuss in depth a number of important selected topics. The seven chap ters fall into two categories. Chapters 2, 3, and 7 are comprehensive surveys on, respectively, the whole field of image sequence analysis, efficient coding of image sequences, and the processing of medical image sequences. In Chapters 1, 4, 5, and 6 the authors present mainly results of their own research on, respectively, motion estimation, noise reduction in image sequences, moving object extraction, and occlusion.

This book was released on 1990 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a method for the estimation of scene structure and camera motion from a sequence of images. This approach achieves fundamental improvements over existing methods in the following respects: (1) No computation of optical flow or feature correspondence is required. Structure and motion are obtained directly from gradients of image brightness; (2) The method processes image sequences of arbitrary length and exploits the inherent redundancy for a significant reduction in error over time; and (3) No restrictions or assumptions are made about the camera motion or the the surface structure. Both quantities are fully recovered using this method. Our method combines the direct motion vision approach of Horn, Weldon and Negahdaripour with the theory of recursive estimation. Most importantly: it really works and we show results on a variety of real image sequences. Keywords: Structure estimation; Kalman filters; Artificial intelligence. (kr).

Download or read book Computer Vision Analysis of Image Motion by Variational Methods written by Amar Mitiche and published by Springer Science & Business Media. This book was released on 2013-09-05 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a unified view of image motion analysis under the variational framework. Variational methods, rooted in physics and mechanics, but appearing in many other domains, such as statistics, control, and computer vision, address a problem from an optimization standpoint, i.e., they formulate it as the optimization of an objective function or functional. The methods of image motion analysis described in this book use the calculus of variations to minimize (or maximize) an objective functional which transcribes all of the constraints that characterize the desired motion variables. The book addresses the four core subjects of motion analysis: Motion estimation, detection, tracking, and three-dimensional interpretation. Each topic is covered in a dedicated chapter. The presentation is prefaced by an introductory chapter which discusses the purpose of motion analysis. Further, a chapter is included which gives the basic tools and formulae related to curvature, Euler Lagrange equations, unconstrained descent optimization, and level sets, that the variational image motion processing methods use repeatedly in the book.
