On the basis of changing codes, the compression of image comprehensively adopts both DCT and Huffman Code to reach a good effect. The system directly connects with net through the video taking by USB camera and MPEG-4 compression code.
图像的压缩技术则是在变换编码的基础上,综合应用了DCT和哈夫曼编码两种手段达到了很好的图像压缩效果,通过USB摄像头捕捉视频,经MPEG—4算法压缩编码,系统直接与网络相连,用户使用标准的网络浏览器和流媒体播放程序即可查看远程视频影像。
