噪声图像压缩

问题描述

我有噪声图像...什么是压缩这个图像的最好的方法？它可能有点有损。基于DCT和Wavelet的技术对于这种问题是不利的。
我的想法是产生一些可重复的噪音，然后只存储差异...但我不能找到任何解决方案可重复的噪声图像。

解决方案

好吧，几乎是不可压缩的噪声定义。

当所感知的输出与另一个适用的规则之间没有已知的相关性时，该陈述适用于真实噪声。所以如果你的形象是这样，或建立看起来像是，那么对不起，它是不可压缩的。

I have "noise" image... what is the best way to compress this image ? It can be little lossy. Techniques based on DCT and Wavelet are bad for this sort of problem.My idea was to generate some recreatable noise and then store only differences... but I cant find any solution for recreatable noise images.

解决方案

Well, it's almost the definition of noise to not be compressible.

This statement applies to "real noise", when there is no known correlation between the perceived output and another applicable rule. So if your image is just that, or built to look like it is, then sorry, it's not compressible.
