Abstract :
A new algorithm to compute motion vectors has been developed based on the block-matching approach which uses bands are instead of blocks. The new band-matching algorithm (BDMA) offers better performance than both fixed and variable size block-matching algorithms because it uses fewer vectors and processes parts of the image instead of the whole image. The BDMA then uses edge and texture information to search for a match. Matching results produce a specific vector for the estimated motion. The new algorithm has been evaluated using several standard video images
