Wikipedia:Articles for deletion/Orientation (computer vision)


 * The following discussion is an archived debate of the proposed deletion of the article below. Please do not modify it. Subsequent comments should be made on the appropriate discussion page (such as the article's talk page or in a deletion review).  No further edits should be made to this page.

The result was redirect to Orientation (for now). There is rough agreement below that this article shouldn't persist in its current state. However, we seem to be one or two steps from finalising what should happen with it. In the interests of WP:ATD and preserving history in case it ever gets merged, setting up this redirect back to the main page - however, anyone at any time is welcome to retarget it, or use one of the suggestions below, or just do something totally different that improves this space.

Tagged since 2009, the subject of the article is not sourced (only applications and side concepts are sourced). The writing is so confusing that it is impossible to know what is the topic that the article is supposed to describe D.Lazard (talk) 17:18, 16 July 2021 (UTC)

 * Comment: The article has been completely incomprehensible since October 2009 when it was tagged as such. This implies that no one cares enough to want to improve it. It's so incomprehensible that I think it would have to be a start-from-scratch job; in its current state, I can't imagine who the readership are supposed to be. It would be helpful were an expert on computer graphics to give an opinion on whether there's a need for an article on this subject. If Yes, I'd say reduce this to a stub and hope someone works on it; if No, then delete. Elemimele (talk) 19:42, 16 July 2021 (UTC)


 * Comment There are multiple concepts of orientation in computer vision:
 * local orientation estimation - the orientation of anisotropy in the neighborhood of a pixel, such as the gradient direction in edge detection, as mentioned in Edge_detection
 * Object orientation estimation - the orientation of an object within an image. This is computed in Pose (computer vision) estimation.
 * Image orientation estimation - what is the global orientation of a whole image? This is useful for photo orientation, or a robot determining its attitude. I don't know if we have a good article for this. It is described in, e.g., Scale-invariant_feature_transform and Image registration.
 * Given the multiple concepts of orientation in computer vision, either a disambiguation page or a broad concept article may be the best approach. -- 11:25, 17 July 2021 (UTC)
 * In the case of a dab page, as Orientation is already a dab page, which links to this article, the disambiguation should be done in a section of Orientation, and this article should become a redirect to this section. D.Lazard (talk) 11:50, 17 July 2021 (UTC)
