Talk:Richardson-Lucy deconvolution

From Wikipedia, the free encyclopedia

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 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)

[edit] 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. Chrisjohnson 00:18, 8 April 2007 (UTC)

[edit] Layman description

I study computer sciences, and was assigned a paper about this algorithm. I used MATLAB's implementation to demonstrate it in action, but my teachers are now requiring a layman's explanation of the algorithm. Does anybody know where I can find such a thing, or if it's even possible to explain it without advanced math? Mfuhlendorf 8 November 2007 Thanks.
