一、经典编码技术本世纪５０年代初，通过对图像自相关函数的研究确认，图像是一类具有很强相关性的信源。为图像压缩编码提供了根据，并从此开始了第一代图像编码的研究，在这一阶段，其压缩技术主要分为预测编码和变换编码两大类。所谓预测编码是利用信号间的相关性将每... First, the classic encoding technology In the early 50s of this century, through the image autocorrelation function to confirm that the image is a type of source with a strong correlation. Which provides the basis for image compression coding, and from this began the first generation of image coding research, at this stage, its compression technology is mainly divided into two categories: predictive coding and transform coding. The so-called predictive coding is the use of signal correlation ...
