DSRA: A block matching algorithm for near-real-time video encoding 

[[abstract]]The correlations of motion vectors between neighboring image blocks have long been applied to improve the efficiency of block matching algorithms. In this paper, a block matching algorithm with a dynamic search range is presented. The search range is adjusted based on the correlations of the motion vectors between neighboring blocks. It is shown by simulation results that the proposed method can speed an MPEG-1 encoding system up to a ratio of 13.3 and increases the bit-rate only of 0.025 bpp, in average. It is therefore beneficial to embed the proposed method into a motion-based encoding system.[[note]]SC
