Threshold Selection Algorithm of Variable Block for H.264 Inter-coding
Tong Wu · Jisuanji gongcheng · 2009
A threshold selection algorithm is presented to effectively predict vector and reduce the complexity of Motion Estimation(ME). Whether the current block is or not the Predicted Vector Block(PVB) is decided by setting up a threshold, and some decisions on the optimization PVB are made in order to terminate the ME process as early as possible. Compared with the UMHexagonS algorithm, the performance of the algorithm is testified on the JM10.2 platform. Experimental results show that the coding time is approximately saved by 84% and the coding efficiency is greatly raised while the degradation of video quality is negligible for real-time application demand.
