Talk:Image derivative

Article doesn't explain what Image Derivatives are

The article goes right into how to compute image derivatives without any kind of introduction explaining what they are, why they're useful, etc. — Preceding unsigned comment added by The-Penultimate-Defenestrator (talk • contribs) 01:32, 26 May 2016 (UTC)

Notability

Hast derivatives are not notable enough IMHO. The cited article from 2014 has only 3 citations. It seems like self advertisement and should be removed. — Preceding unsigned comment added by 213.16.80.50 (talk) 15:08, 17 March 2017 (UTC)

Examples are in the proprietary code of a commercial vendor

Please replace examples using Matlab code with something I do not have to purchase in order to verify. Hpfeil (talk) 20:40, 17 February 2021 (UTC)
