Based on analyzing the UMHexagonS algorithm,makes the improvement to the UMHexagonS algorithm,reflected in two aspects: firstly,dynamic search Window is adopted to replace the fixed search window which is helpful to reduce algorithm complexity and improves the computational accuracy.Secondly,adds an early termination in case that it enters the redundant search after the initial search point prediction with good effects.Experiment with some typical video sequences shows that compared to the original UMHexagonS algorithm,this new algorithm can save 10～30% motion estimation time and enhance the real time performance of the encoder.
