Abstract:
Block matching algorithms for motion estimation were developed in order to obtain reasonable motion estimation efficiency with minimum computational cost. Although the gain in the computational complexity is significant these algorithms have less precision in estimation than the basic block matching motion estimation algorithm, i.e., the Full Search algorithm. The proposed motion estimation method can be used with any of the existing block matching algorithms and brings an increase of estimation precision with small increase of the global computational cost. This improvement is achieved by choosing the search window size depending of the ration between the frame size and the motion area size.
