Conventional coding system using translation only motion estimation and compensation system cannot efficiently handle complex inter-frame motion activity including scaling, rotation and various forms of distortion. In this paper, we propose a local affine motion prediction method, which manages to enhance the inter-frame image prediction quality using the conventional motion vectors. Our method is...
H.264/advanced video coding (AVC) decoding complexity modeling and applications are examined in this paper. We focus on complex modeling of spatial and temporal compensations achieved by a rich set of inter and intra-prediction modes of H.264/AVC. We study the relationship between motion vectors (MV), frame sizes, and distributions of selected reference frames, which are highly related to cache management...
In this paper, we propose a pooled zero vector coding scheme for improving coding efficiency of moving pictures. Since motion vector takes considerable portion of compressed bitstream, its higher compression is very essential for improving the coding efficiency of moving pictures beyond that given by the state-of-the-art coder of H.264/AVC. Since there is considerable correlation among motion vectors...
Complexity modeling of spatial-temporal compensations in H.264/AVC decoding is performed by examining a rich set of inter- and intra-prediction modes. Specifically, we study the relationship between motion vectors, frame sizes and properties of reference frames since they are related to cache management efficiency. The proposed models provide good estimation results for test video bit streams over...
