Because of the limitation of bandwidth, video coder needs one stream of high- resolution for local storage and one steam of low-resolution for network transmission. Reusing high-resolution stream is the very point when designing for improving efficiency. Based on the analysis of the existing methods for motion vector synthesis with using four standard testing sequences, we proposed a Double Predictor...
A kind of fast block-matching algorithms which do not introduce any prediction error as compared with the full-search algorithm is to reduce the number of necessary matching evaluations for every searching point in the search window based on partial distortion elimination (PDE), among which winner-update search (WUS) algorithm is a well-known technique. Based on correlation characteristic between...
Intra 4times4 is one of the two primary intra prediction types supported in H.264/AVC. For intra 4times4 prediction, eight modes are to capture orientations of images with DC mode to reflect flat regions. Therefore the smoothly-varying regions which are very common in ordinary images can not be well decorrelated. In this paper, to improve decorrelation performance of intra 4times4 prediction, we propose...
