【摘要】 针对煤矿井下这一特殊环境下的视频监控要求和视频序列特点,提出了基于H.264/AVC标准的煤矿井下视频编码的一种帧内预测模式快速算法。通过仿真实验证明,该算法与原H.264/AVC标准算法相比,对于IPPPP类型帧序列,可节约15%左右的编码时间;对于全I帧视频序列,可节约30%左右的编码时间,而视频质量(PSNR)和码率几乎不变。更多还原

【Abstract】 In view of video monitoring requirements and the specialty of video sequences in the special environment of coal mine underground,a fast mode intraprediction algorithm for video encoding in coal mine underground based on H.264/AVC is proposed.Proved by data in simulating,this algorithm could save about 15% encoding time for IPPP frame sequences and about 30% encoding time for all I frame sequences compared to the original H.264/AVC standard algorithm with almost the same bit rates and video quality(PSNR).更多还原
