视频图像压缩编码标准分析

模拟视频数字化后,数据量巨大。在对其进行实时处理时,对存储容量、传输带宽及计算机的处理能力提出了不切实际的要求,从而使数字化成为不可能。因此,可采用数据压缩技术,将那些对人眼感知图像不太重要的东西和图像中的冗余成分抛弃,从而缩减存储、传输和处理的数据量。这样就出现一系列的视频压缩编码标准。就视频压缩标准,以及图像压缩中所采用的相关技术进行介绍,并重点对MPEG4的原理进行讲解。

Analyzing Video Image Compression Standard

After simulation video becomes digital,data stream is huge.When the real-time handle is implemented,it poses a great impractical challenge towards storage and transport brand,which makes digitalization impossible.So,it can uses data compressing technique to cut those unimportant to an image and then discard them,which formulates a standard for video compress encoding.This paper focuses on the video compress-encoding standard,and discusses the related techniques,and describes the theory of MPEG-4 in detailed.
