Additional, more common use of the term "color mapping"

[edit]

"Color mapping" is probably most-commonly used for mapping data to color (e.g., for daily weather maps, hazard maps, standard plots like heat maps, or many other applications). I believe this should be reflected in this page, either by adding this fact, and related background information, or by creating two separate pages for "Color mapping (photography)" and "Color mapping (data)". Any thoughts on this? — Preceding unsigned comment added by OneTwoThreeHoneyBee (talkcontribs) 08:59, 11 January 2021 (UTC)[reply]

I don't believe this article should have the title 'color mapping', it should be called 'image color transfer'. Here is a justification. Open Google in incognito mode and search for 'color mapping' and then for 'image color transfer'. The second search produces results that are far more closely aligned to the contents of this article than the first search. EcclesMan (talk) 15:23, 3 March 2023 (UTC)[reply]

Requested move 15 March 2023

[edit]
The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review after discussing it on the closer's talk page. No further edits should be made to this discussion.

The result of the move request was: moved. Based on minimal participation (even after relisting), this request is termed as unopposed. (closed by non-admin page mover) ❯❯❯ Raydann(Talk) 17:44, 29 March 2023 (UTC)[reply]


Color mappingImage color transfer – The existing title ‘Color mapping’ is ambiguous. It could for example relate to the process where an image is mapped from one color space to another color space. The article itself currently gives the warning ‘Not to be confused with Pseudo color.’ This warning can be removed if the name is changed as suggested. If a search is performed for ‘color mapping’ using Google in ‘incognito mode’ the majority of the search results are unrelated to the topic here. If having performed the search ‘images’ are selected then only a small minority of the images relate directly to this topic. The converse is true if a search is performed for ‘image color transfer’. The name colour mapping’ is somewhat outdated and this might explain why the content is not as up to date as it should be. (Declaration of interest: if you type 'image color transfer' into Google in incognito mode my web app is the top item) EcclesMan (talk) 16:29, 15 March 2023 (UTC) — Relisting. {{ping|ClydeFranklin}} (t/c) 17:02, 22 March 2023 (UTC)[reply]

Relisting comment: This could be moved as unopposed, but this seems like a controversial move which is worth a relist. {{ping|ClydeFranklin}} (t/c) 17:02, 22 March 2023 (UTC)[reply]

Rationale for the sentence on terminological confusion and incorrect software

[edit]

I carefully considered the inclusion of the sentence: “Because of confusion over this terminology, some software has been released into the public domain with incorrect functionality.”

My intent was to provide an appropriate warning to readers—particularly those unfamiliar with the field of Image Colour Transfer—that some widely circulated implementations contain functional errors arising from a misunderstanding of terminology. However, I was also mindful not to unduly highlight a particular author or project. The most notable example involves a well-known blogger who generally produces informative and technically sound content. It would be inappropriate to single out that individual directly in this context. The associated blog post and GitHub repository have received considerable attention. The GitHub project currently has over 500 stars—far more than some other technically more accurate and/or more advanced implementations of the same algorithm. For an extended period, the blog appeared at the top of Google search results for “Image Colour Transfer.” Given its prominence, the implementation has had attracted high visibility despite known issues.

Rather than directly naming the project, I have opted for a compromise: referencing a specific comment within the GitHub repository. That comment introduces a switch variable that allows users to choose between two alternative formulae—when, clearly, only one of them can be correct. The discussion there makes it evident that the ambiguity arises from confusion over which of the two images involved is the "source" and which is the "target."

If other editors feel a more direct citation is warranted, they are free to trace the reference back to the full repository or blog. My primary concern is to ensure that Wikipedia readers are made aware that some well-known software implementations of Image Colour Transfer may be based on incorrect assumptions, and that due caution should be exercised when using or evaluating such tools. (Please be aware, though, that comments on both the GitHub repository and the blog involve some conflicting discussions and it would be desirable, if possible, not to invite dispute on these pages.)
