Abstract :
3-D recursive search block matching is a conventional motion estimation method based on block matching. The algorithm is more efficient and effective than a full-search algorithm. However, the algorithm tends to fail to detect the true motion when the spatiotemporal smoothness of motion is not held. In this paper, we propose a new motion estimation algorithm introducing hierarchical search strategy.
