Based on the algorithm of UMHexagonS,a motion estimation algorithm based on motion classification and multi-pattern was proposed which solved the problem of searching too many points and low searching speed of slow-moving video sequence.Distribution features of the motion vector were used,and motion blocks were categorized into different types according to speed,and then the appropriate pattern and strategies for motion blocks were selected to search.Based on the algorithm,the video transmission on mobile device was realized.The results of experiment show that compared with the UMHexagonS,the proposed algorithm can reduce the time of motion estimation obviously and improve coding efficiency significantly on the premise of ensuring the image quality.
