摘　　要：以CC ITT建议的H.261为标准在M atlab 6.5下,利用M atlab以矩阵作为基本运算单元的特点,及其独特的图像处理函数,实现了视频序列的编码,得到符合H.261语法结构的码流。同时建立了完好的人机交互界面。实验结果表明,以此建立的视频序列编码过程简洁,结果具有说服力,验证了在M atlab下进行视频序列编码的可行性,说明M atlab不仅可对静止图像处理,也可以用于视频序列的编码。Matrix is the basic operation unit of Matlab,which has a series of particular image processing function. According to CCITT recommendation H. 261. video sequences coding is realized in the circumstances of Matlab 6.5 coding.stream is acquired in conformity with syntax of H.261. Perfect alternating interface is also built up. Experiment result suggests that the video sequences coding process is simple and the result is convincing. Feasibility for video sequences coding in the circumstances of Matlab 6.5 is verified. It suggests that Matlab can not only be used in still images＇ processing,but also fit for video coding.
