For any video-based applications, estimating the motion of dynamic object(s) inside a video frame is required to be as accurate as possible. Different standard methods (block and mesh based) of motion estimations have their own merits and demerits. Block based approach gives reasonably good performance in terms of accuracy with limited amount of bit rate but suffers from discontinuity of motion at...
We propose a simple fast block-matching algorithm (BMA) based on the direction of the predicted motion vector called directional & adaptive diamond search by adaptive pattern switching (DADS-APS). The proposal method has two sequential search steps, including 1) an initial search, and 2) a refinement search for the local area. Adaptive pattern switching (APS) is proposed for the initial search...
