A new motion estimatiion algorithm based on space relation for frame rate up conversion

摘要

In this paper, a novel motion estimation and compensation algorithm for frame rate up conversion is presented. Compared to conventional motion estimation methods, motion vectors are processed by different approaches for static region or internal object region and moving boundary of video stream in this proposed algorithm. In the static or internal object region, motion vectors are decided according to the interaction principle between adjacent blocks and easily obtained by the adjacent motion vectors; while for the moving boundary, motion vectors are firstly calculated according to the adjacent blocks, and thenn the algorithm detects the movement of block in the region by SAD values, finally, the motion vectors of moving blocks are refined and corrected.
