来处理呀？ matlab里的blind-deblur 很不好用呀，很多ring artifact.

nothing, which means you can't really "improve" the resolution of a photo.
You can only make things more "obvious" to your eyes, while in the process
the best you can hope is that you don't lose any information.

发帖数: 157 | 3 我就是想知道比较普遍的怎么来估算PSF，再怎么来做deconvolution，把图片弄得清楚
点。这个过程，参数的选择，模型的运用，会增强一部分信号，也带来一些artifact.
简单的说，如果真实的PSF is gaussian with Delta, 就算我估算的是gaussian with
Delta/2,那应该也会把图像变清楚点了.
