技术资料 带码率控制的近无损图像压缩
数字图像的压缩是解决图像数据量大、存储和传输困难的基本措施。图像压缩的方法很多，一般可分为有损压缩和无损压缩两大类。有损压缩允许一定程度的信息丢失，在满足实际应用的条件下能够取得较高的压缩比；无损压缩不允许信息丢失，但是压缩比难以提高。在医学图像、遥感图像等应用领域，对于图像的压缩比和失真度都有着较 ...

DIGITAL IMAGERY is pervasive in our world today. Consequently,
standards for the efficient representation and
interchange of digital images are essential. To date, some of
the most successful still image compression standards have resulted
from the ongoing work of the Joint Photographic Experts
