这篇博客讨论了Richardson-Lucy去卷积算法，涉及到噪声处理、原始论文引用、简单解释以及MATLAB实现。在噪声存在的情况下，像素表示涉及点扩散函数和潜在图像，文章中提到MATLAB提供了去卷积函数。同时，对于算法的直观理解，有人提出疑问并进行了自我解答，指出卷积核元素之和为1是关键。

Talk:Richardson–Lucy deconvolution

The paragraph says "In the presence of noise, pixels in the observed image can be represented in terms of the point spread function and the latent image as..." but I can't see the noise in the equation. Does it lack an aditive term (+ epsilon) that takes into account Photon noise?

I think the equations here are correct: the noise is modelled by having {\displaystyle u_{i}} $u_{i}$ as a random variable with a Poisson distribution. This becomes clear in the derivation of the iteration, something which I plan to add to the article. Chrisjohnson 00:18, 8 April 2007 (UTC)

1.Original paper reference

Should not the reference to the original paper in this article be to the "Astronomical Journal", not just to the "AJ"? (I've seen confusions of this sort before - example: "APJ" or "ApJ", when "Astrophysical Journal" - rather than "Applications Journal" - was meant.) Hair Commodore 21:44, 18 December 2006 (UTC)

Googling reveals that the Astronomical Journal refers to itself as AJ or Astron. J. I've put the latter into the article.
