Motion estimation is important for compression of video sequences. In this paper a new block motion estimation algorithm proposed. In the proposed method, the motion vector of previous frame are used to predict the initial motion vector and the search direction. The extent of search region is determined by predicted motion vector and motion vectors of four casual neighbours in the current frame. Results shows significant speed-up compared to existing ones.
