Book excerpt: Multi-Frame Motion-Compensated Prediction for Video Transmission presents a comprehensive description of a new technique in video coding and transmission. The work presented in the book has had a very strong impact on video coding standards and will be of interest to practicing engineers and researchers as well as academics. The multi-frame technique and the Lagrangian coder control have been adopted by the ITU-T as an integral part of the well known H.263 standard and are were adopted in the ongoing H.26L project of the ITU-T Video Coding Experts Group. This work will interest researchers and students in the field of video coding and transmission. Moreover, engineers in the field will also be interested since an integral part of the well known H.263 standard is based on the presented material.

Download or read book Multiple Reference Motion Compensation written by Athanasios Leontaris and published by Now Publishers Inc. This book was released on 2009 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motion compensation exploits temporal correlation in a video sequence to yield high compression efficiency. Multiple reference frame motion compensation is an extension of motion compensation that exploits temporal correlation over a longer time scale. Devised mainly for increasing compression efficiency, it exhibits useful properties such as enhanced error resilience and error concealment. Multiple Reference Motion Compensation: A Tutorial Introduction and Survey explores different aspects of multiple reference frame motion compensation, including multihypothesis prediction, global motion prediction, improved error resilience and concealment for multiple references, and algorithms for fast motion estimation in the context of multiple reference frame video encoders

This book was released on 2006-04-18 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Appendices 133 A Mathematical Results 133 A.1 Singularities of the Displacement Error Covariance Matrix 133 A.2 A Class of Matrices and their Eigenvalues 134 A.3 Inverse of the Power Spectral Density Matrix 134 A.4 Power Spectral Density of a Frame 136 Glossary 137 References 141 Index 159 Preface This book aims to capture recent advances in motion compensation for - ficient video compression. It investigates linearly combined motion comp- sated signals and generalizes the well known superposition for bidirectional prediction in B-pictures. The number of superimposed signals and the sel- tion of reference pictures will be important aspects of the discussion. The application oriented part of the book employs this concept to the well known ITU-T Recommendation H.263 and continues with the improvements by superimposed motion-compensated signals for the emerging ITU-T R- ommendation H.264 and ISO/IEC MPEG-4 (Part 10). In addition, it discusses a new approach for wavelet-based video coding. This technology is currently investigated by MPEG to develop a new video compression standard for the mid-term future.

Download or read book Quality Drift and Delay Issues in Multiple Reference Frame Video Coding written by Athanasios Leontaris and published by . This book was released on 2006 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The efficiency of modern video compression is largely a result of motion-compensated prediction (MCP) that exploits temporal correlation in the signal. Multiple reference frames for MCP improve compression efficiency and error resilience and require new paradigms in (a) reference frame selection, (b) bit rate allocation among frames, (c) application to scalable video codecs, and (d) delay requirements of these codecs. We study all four of these aspects in this dissertation. A dual-frame video coder employs two past reference frames (one short-term frame and one long-term frame available for prediction) for MCP. Dual-frame video codecs benefit greatly from near-optimal intra/inter mode switching within a rate- distortion framework. We show that such a scheme improves the error resilience of the coder. We improve the mode-switching algorithm with the use of half-pel motion vectors. Furthermore, we investigate the effect of feedback in making more efficient mode-switching decisions. In previous work, it was shown that uneven assignment of quality to frames, to create high-quality (HQ) long-term reference frames, can enhance the performance of a dual-frame encoder. Here, we demonstrate the performance advantages of optimal mode selection among such HQ frames for video transmission over noisy channels. We investigate dual frame prediction for both base and enhancement layers of an SNR scalable video coder, with pulsed quality allocation in the base layer. Furthermore, a per-pixel drift estimation algorithm is introduced, where the encoder estimates the potential drift at the enhancement layer recursively and chooses coding modes accordingly. Real-time video applications require tight bounds on end-to-end delay. Hierarchical bi-directional prediction requires buffering in the encoder input and output. Dual frame prediction with pulsed quality requires buffering at the encoder output. Both codecs involve uneven bit rate allocation that affects the encoder and decoder buffering requirements. We derive an efficient rate allocation for hierarchical B-pictures, and investigate the trade-off between delay and compression efficiency. Furthermore, we discuss effect of the temporal prediction distance and prediction branch truncation.

Available in PDF, EPUB and Kindle. Book excerpt: In order for wireless devices to function, the signals must be coded in standard ways so that the sender and the receiver can communicate. This area of video source coding is one of the key challenges in the worldwide push to deliver full video communications over wireless devices. Video Coding for Mobile Communications reviews current progress in this field and looks at how to solve some of the most important technology issues in the months and years ahead. The vision of being able to communicate from anywhere, at any time, and with any type of information is on its way to becoming reality. This natural convergence of mobile communications and multimedia is a field that is expected to achieve unprecedented growth and commercial success. Current wireless communication devices support a number of basic multimedia services (voice, messages, basic internet access), but have coding problems that need to be solved before "real-time" mobile video communication can be achieved. - Addresses the emerging field of mobile multimedia communications

Available in PDF, EPUB and Kindle. Book excerpt: What is Motion Estimation In computer vision and image processing, motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another; usually from adjacent frames in a video sequence. It is an ill-posed problem as the motion happens in three dimensions (3D) but the images are a projection of the 3D scene onto a 2D plane. The motion vectors may relate to the whole image or specific parts, such as rectangular blocks, arbitrary shaped patches or even per pixel. The motion vectors may be represented by a translational model or many other models that can approximate the motion of a real video camera, such as rotation and translation in all three dimensions and zoom.
