| Abstract: | In this paper, based on the study of the principles of the UMHexagonS algorithm, an improved method is proposed,in which the idea of a new adaptive factor is introduced in initial search point prediction step for early termination. Simulation Results show that the im- proved UMHexagonS algorithm can averagely Saved coding time with minimal loss in bit rate and reconstructed quality compared with those of the original UMHexagonS algorithm. |
