【Abstract】This paper presents a new fast motion estimation algorithm based on moving direction prediction, called Moving Direction Prediction (MDP) algorithm in which the high correlation of adjacently blocks’ motion vectors and the center-biased characteristic of motion vectors in image sequences are used. The algorithm designs four kinds of patterns and selects patterns to process the image according to its motion direction predicted by referenced motion vectors. Experimental results show that the algorithm excels other traditional algorithms in speed and veracity.
