—In this paper, we propose two cross-diamond-hexagonal search (CDHS) algorithms, which differ from each other by their sizes of hexagonal search patterns. These algorithms basically employ two cross-shaped search patterns consecutively in the very beginning steps and switch using diamond-shaped patterns. To further reduce the checking points, two pairs of(More)
In order to fit the small cross-center-biased characteristic of the real world video sequences, an improved version of the well-known cross-diamond search algorithm (CDS) is proposed in this paper. Unlike traditional search pattern, such as square, diamond or cross – all are in vertically and horizontally symmetric shape, the kite-cross-diamond search(More)
Search patterns and the center-biased characteristics of motion vector distribution (MVD) have large impact on both searching speed and quality of block motion estimation. In this paper, we propose a novel algorithm using a rood-shaped search pattern as the initial step and large/small diamond search patterns as the subsequent steps for fast block motion(More)
The quality of the synthesized views by Depth Image Based Rendering (DIBR) highly depends on the accuracy of the depth map, especially the alignment of object boundaries of texture image. In practice, the misalignment of sharp depth map edges is the major cause of the annoying artifacts at the disoccluded regions of the synthesized views. Conventional(More)
– The quality against speed control for real-time video applications, such as the speed-oriented video conferencing or the high quality video entertainment, usually absents from many traditional fast block motion estimators. In this paper, a novel block-matching algorithm for fast motion estimation named generalized partial distortion search algorithm(More)
In this paper, we propose a kite-cross-diamond search (KCDS) algorithm, which is an improved version of the well-known cross-diamond search (CDS) algorithm and small cross-diamond search (SCDS) algorithm. Unlike traditional search pattern in block matching algorithm, such as square, diamond or cross – all are in vertically and horizontally symmetric shape,(More)
