1.前言 音频世界可用CD代表,正在形成数字中心。但成像世界还不行。这是因为图象信号的信息量是音频信号的100倍以上,很难数字化。近年来,由于以MPEG为代表的高效率编码技术的利用,迅速地向数字化发展。 下面介绍有代表性的图象高效率编码技术的概要,并探究其应用和存在的问
1. Introduction The audio world is represented by a CD, forming a digital hub. But the imaging world is not enough. This is because the amount of information of an image signal is more than 100 times that of an audio signal, making it difficult to digitize. In recent years, due to the use of high-efficiency encoding technology represented by MPEG, the digitalization has been rapidly developed. Here is a brief overview of a representative high-efficiency coding technique for images, and to explore its applications and existential questions
