An Improvement of Unsymmetrical-Cross Multi-Hexagon-grid Search algorithm
In this paper, we present an new algorithm based on the Unsymmetrical-cross Multi-Hexagon-grid Search (UMHexagonS) algorithm and and the Fast Directional Gradient Descent Search (FDGDS). The experiment results show that this new algorithm can reduce the motion estimation time with just a very minor bit rate increase and almost the same image quality.
Keywords: Video compression, block matching, improvement, motion estimation, video coding, UMHexagonS.
