Fast inter-mode decision algorithm based on UMHexagonS
基于UMHexagonS的快速帧间模式选择算法

Fast inter-mode decision algorithm based on "Unsymmetrical cross Hexagon grid Search" (UMHexagonS) was improved in this paper. The priority estimation of SKIP mode and the inter-mode decision based on image detail were employed. Experimental results show that the one-frame scramble time of fast inter-mode decision, compared with UMHexagonS algorithm, is reduced by 57.48% with negligible loss of peak signal-to-noise ratio.
