Based on the study of the principle of the UMHexagonS algorithm, combined with the source code of JM 12.4, an improved method is proposed to reduce the time of motion estimation with minimal loss in bitrates and reconstructed quality compared with those of the original UMHexagonS algorithm. By improving the inter mode selection of UMHeaxagonS algorithm, the redundant search points are reduced. The results show that the adaptive algorithm can reduce 10% of motion estimation with the original performance of the original UMHexagonS algorithm.
