摘要
利用从H.264解码中得到的帧内预测方向和非零DCT系数来估计AVS编码中的预测方向,以减少AVS帧内预测所需的时间。仿真结果显示新算法可以在保持较好图像质量的同时节省至少56%的运算量。
The prediction directions and the number of non-zero coefficients obtained from the H.264 decoder are used to estimate the prediction directions in AVS encoder to save the time used for AVS intra prediction. The simulation results show that the proposed algorithm is able to maintain a good picture quality while reducing at least 56% of computation.
