摘要
The main factor that impacts the implementation and application of the latest video coding standard H.264/AVC is the rapid decline encoding speed which is caused by the cost of increased computational complexity. Reducing time-consuming of motion estimation is the key to improve encoding efficiency. In this paper, according to UMHexagonS algorithm, a method of motion vector distribution prediction is proposed and combines with designed patterns to achieve adaptive sub-regional searching. Simulation results show that the proposed motion estimation scheme achieves reducing 21.40% motion estimation encoding time with a good rate-distortion performance compared with UMHexagonS algorithm in JM18.4. The proposed algorithm improves the performance of real-time encoding. © 2013 ACADEMY PUBLISHER.
