An Improvement on the Simplified UMHexagonS Algorithm
Xiangning Chen · Microprocessors · 2008
The video coding standards H.264 have adopted Simplified UMHexagonS Algorithm as an Improved and Simplified Fast Motion Estimation Method for integer pel motion estimation.In this paper,based on the study of the principles of Simplified UMHexagonS algorithm,an improved method is proposed: First we check two kinds predictors,then search in different predictions domain,and after cross search which satisfy intensive search condition we add a converge judgement.Results show that the improved Simplified UMHexagonS algorithm can reduce search points and reconstructed quality compared with those of the origoinal Simplified UMHexagonS Algorithm.
