Abstract: There are some corners in motion regions, resulting in low executive efficiency and precision, when using corners to compute the motion estimation. For solving this problem, motion estimation algorithm based on non-motion region partitions is proposed in this paper. The reference frame image is divided into non-motion regions and motion regions by grid method. Corners of non-motion regions are selected in the reference frame image, and matched with corners of the current frame image. After removing the mismatch of corners by using distance invariant criterion, motion vector is estimated by residual corners. Experimental results show that the algorithm can improve the precision and executive efficiency.
