Optimization of Integer Transform and Quantization in H.264
分析研究了H.264中比较耗时的整数变换与量化的过程，设计全零块检测算法和基于实验的QP值选择策略，优化整数变换与量化过程。实验结果表明，在保证视频质量满意度的前提下，优化算法提高了视频编码速率，增强了视频编码的实时性。
fter analyzing the time-consuming integer transform and quantization processes in H.264, an all-zero block detection algorithm and an experiment based decision strategy for QP are developed so as to optimize integer transform and quantization procedure. Experimental results show that the optimization algorithm speeds up the video encoding and improves the real-time performance on the premise of video quality satisfaction.
