| 摘 要： | 帧内预测模式选择是影响H．264编码速率的主要因素。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。实验结果表明：用全I帧编码，该算法在图像质量和输出码率基本不变的情况下，节省编码时间约12％。

| Abstract: | Mode selection of intra-prediction is the main factor affecting the coding rate of H. 264. In this paper, an improved algorithm is proposed on the base of analyzing the research status of the fast algorithm of H. 264 intra-prediction. Experimental results show that coding with all intra frame, the proposed algorithm introduces slight PSNR degradation and bit rate increase but saves around 12% of the total encoding time. |
