摘要
文章在分析H.261视频编码器和小波变换理论的基础上,设计一种改进的视频编解码器,在帧间编码模式中,采用基于小波变换的运动估计。实验结果表明这种编码器较传统的H.261性能有较大的改善。
The increasing demands for videophone,HDTV,multimedia and information communication in recent years enhance the importance of effective video image coding technique. Based on the analysis and comprehension of the H.261 and wavelet transform theory,this paper designed an improved coding mode. In the interframe coding mode,motion estimation based on the wavelet transform is adopted. Experimental results show the priority of the improved video coding over H.261.
