| 摘 要： | 帧内预测模式选择是影响H.264编码速率的瓶颈问题.在分析H.264帧内预测模式选择快速算法研究现状的基础上,提出一种改进算法,利用空域特征筛选Intra_4×4预测模式并结合提前中止策略来减少不必要的模式选择计算.实验结果表明:该算法在基本保持编码性能的情况下使得帧内编码时间大为降低.

| Abstract: | Intra-prediction mode decision is the bottleneck in H.264 encoding rate.In this paper,an improved algorithm is proposed on the basis of the analysis of the study status of fast algorithm of intra-prediction mode decision for H.264.The feature in spatial domain is utilized to filter out some prediction modes for Intra_4 x 4 and early termination technology is employed to avoid unnecessary computations of mode decision.Experimental results show that the proposed algorithm decreases the time of intra coding si... |
