Talk:Blind deconvolution

}}

This article is presently focused on blind image restoration. There should be some division of this from blind deconvolution of time domain signals (sound, radio signals, etc.) which is a pretty important field.

No description of what L K and N are

This article mentions an essential condition that is related to parameters L, K and N, but doesn't say what those parameters are our where the condition comes from. The example section where these are first meiner is strange as it only has the distorted image. Yo have no idea what to make of that image until much father down the article. 73.15.169.24 (talk) 15:50, 30 October 2021 (UTC)

:Agreed. Very confusing. Can anyone give a reference elaborating on these terms so we can add it to the article? 2601:98A:4203:77C0:EDC4:950D:CAD6:CB4E (talk) 20:38, 28 July 2022 (UTC)

::It seems the information was removed in the most recent edit. Can we fix that? Not clear why it was deleted. 2601:98A:4203:77C0:EDC4:950D:CAD6:CB4E (talk) 20:44, 28 July 2022 (UTC)

:::This seems to be taken from the following source: https://ijrdst.org/public/uploads/paper/319_approvedpaper.pdf Although I cannot say whether it is the converse, i.e. that this "source" has grabbed some historically more complete wiki entry. Anyway, it DOES clarify those parameters, but I'm reluctant to simply copy those into the article, as I'm not clear on whether a simple reference is sufficient for this not to be plagiarism etc. I just thought I'd drop this information for posterity.

:::"Limitation of Blind deconvolution is that both input image and blur kernel must live in fixed subspace. That means input image, represented by w, has to be written as w=Bh, where B is random matrix of size L by K (K=K +N. " Bforsbe (talk) 06:56, 6 May 2025 (UTC)

Use of Lena

Should we change the example image from Lena to something else? Many academic publications no longer accept papers using this image for both technical reasons (it is a poorly digitized scan of an old magazine print) and because of the overlap of the use of this image with the undesirable history of a shift in computer science being a non-gendered environment to one dominated by males.
