Article doesn't explain what Image Derivatives are edit

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 (talkcontribs) 01:32, 26 May 2016 (UTC)Reply

Notability edit

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)Reply

Examples are in the proprietary code of a commercial vendor edit

Please replace examples using Matlab code with something I do not have to purchase in order to verify. [1] Hpfeil (talk) 20:40, 17 February 2021 (UTC)Reply
