基于自适应混合变换编码的二值图像处理

为了提高图象的处理质量，要求编码算法简单，处理速度快，同时使压缩信息损失最小，文中所给出的算法，对被处理图象进行自适应分块，再通过区域编码与阈值编码相结和，进而进行自适应混合变换编码，最终达到了提高图象处理质量的目的，实验结果表明，这种方法压缩损失小，图像处理质量较高。

Binary Images Processing Based on Adaptation to Mixture Transform Coding

To enhance quality of image processing, it is demanded that coding algorithm should be simplified and the speed of image processing should be faster,and information loss on image compressed should be minimum.Adaptive segmentation is given for image which to be processed.Region coding is combined with threshold coding.Adaptation to mixture transform coding is fulfilled.Results of simulation shows that with this method coding loss witch images are compressed is mined and quantity of image processing is good.
