Fast Computational Four-Neighborhood Search Algorithm For Block matching Motion Estimation
نویسنده
چکیده
The Motion estimation is an effective method for removing temporal redundancyfound in video sequence compression. Block Matching algorithm has been widely used in motion estimation and a number of fast algorithms have proposed to reduce the computational complexity of BMA. In this paper we propose a new search strategy for fast block matching based on Four-Neighborhood Search (FNS) and fast computational strategy, this new algorithm can significantly speed up the computation of the block matching by reducing the number of checked points and the time computational. Results have been shown that 89% to 93% of operations can be saved while maintaining the quality of video relative to full search algorithm. Keywords– Block matching, Motion estimation, Four-neighborhood search.

Adaptive search area for fast motion estimation
In this paper a new method for determining the search area for motion estimation algorithm based on block matching is suggested. In the proposed method the search area is adaptively found for each block of a frame. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of reg...
