背景：要求和选择过程啤酒发展。一种连续色调图像压缩方法，它满足下列要求：a）在或不在。在压缩率和伴随的图像保真度方面的现有技术中，在图像质量等级的范围内，特别是在图像质量等级对原始图像质量等级的范围内，zcd为“非常好”到“优秀”，并且，编码器应该是应用于图像质量等级的参数zable，Y0。atlon（或用户）可以设置DES，RED压缩质量折衷，B）实际上可应用于连续音数字信号的k，nd，medge（1）。e）对于大多数实际目的，不限于图像、颜色空间、像素纵横比，并且不限于具有对场景内容的限制的图像类别，例如复杂度、颜色范围或统计属性，c）具有易处理的计算复杂度，以使得在CPU范围上能够执行可行的软件实现，以及对于要求高性能的应用具有可行成本的硬件实现，
