This book was released on 2016 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work on this thesis then contrives a number of fast algorithms for motion estimation. The adoption of motion vector composition (MV composition) for a fast motion estimation scheme in a low-delay hierarchical P-frame structure is firstly proposed. It expedites the motion estimation process for distant reference frames in the hierarchical P structure. In addition, a vector selection algorithmis tailor-made with the proposed hierarchical P coding scheme to further improve the coding efficiency. Simulation results show that the proposed scheme can deliver a remarkable complexity savings and coding efficiency improvement on coding a frame in low temporal layers of the hierarchical P structure. The rest of this work proposes to perform motion locus prediction before motion estimation. By this motion locus prediction, a suitable search range can be adjusted adaptively for motion estimation. Thanks to the rapid development of MVC and 3D videos, the state-of-the-art 3D coding framework provides multi-view plus depth video (MVD) in which the depth map is additional information to be encoded in the coded bitstreams. Depth maps record the distances of various objects in the scene from a viewpoint. With the depth maps from MVD sequences, we reveal the depth variation and the spatial correlation between blocks as well as the temporal correlation between the depth maps and the motion in texture, motion locus perdition can be achieved for speeding up the texture coding in an HEVC encoder. The depth information brings new room for designing an efficient adaptive search range (ASR) algorithm in HEVC. Simulation results show that the proposed ASR algorithms can offer a significant complexity reduction with negligible loss of coded video quality.

Book Synopsis Multiple Reference Motion Compensation by : Athanasios Leontaris
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

Book excerpt: Image compression refers to the process of reducing the quantity of data used to represent digital images, and is a combination of spatial image compression and temporal motion compensation. Spatial image compression is done by exploiting the spatial redundancy. Temporal motion compensation is done by exploiting the correlation of the pixels in the nearby frame. Images require substantial storage and transmission resources, thus image compression is advantageous to reduce these requirements. The report covers some background of wavelet analysis, data compression and how wavelets have been and can be used for image compression and some of the block matching techniques for motion estimation. In this thesis, investigations have been made to understand the actual mechanism of compression of still images and applying the principle to the video frames. Initially image compression is analyzed using wavelet transform and then it is implemented. In later stages motion estimation techniques are analyzed so as to achieve compression by exploiting the temporal redundancy. Six algorithms for motion estimation are analyzed and compared with each other through their results.
Download or read book Motion Estimation written by Fouad Sabry and published by One Billion Knowledgeable. This book was released on 2024-05-12 with total page 123 pages. 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.

Book Synopsis Block Matching Algorithm for Video Coding by : Mohamed Ghoneim
Download or read book Block Matching Algorithm for Video Coding written by Mohamed Ghoneim and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motion estimation is a key issue in the field of moving images analysis. In the framework of video coding, it is combined with motion compensation in order to exploit the spatio temporal correlation of image sequences along the motion trajectory. It then achieves one of the most important compression factors of a video coder. By dividing each frame into rectangular blocks, motion vectors are obtained via the block matching algorithms (BMA). The full search algorithm (FS) is a brute force BMA. It searches all possible locations inside the search window in the reference frame to provide an optimal solution. However, its high computational complexity makes it often not suitable for real-time implementation. Many fast but sub-optimal algorithms are introduced to improve the performance of video coders. The present book analyses three prospects of improving the quality of existing video coding schemes. Namely, one at a time optimization, adaptive search stagey and feature domain based criteria.
