@Mokubai Contrary to fixer1234's statement, I see tags as a tool to classify both questions and potentially answers. If there won't be an answer using Photoshop, I don't see any benefit to keeping the tag. Tags should make questions easier to find; I stand firm that this question has nothing to do with Photoshop. It's not even the right category of software. I don't fault the user for the misconception, but I'm happy to help point that out. If that sort of edit doesn't fit within the modus operandi of SU, I'm okay with following that lead. Thank you all for your perspective.

@Mokubai in what way did my edit remove important points? I removed the tag but left the mention of Photoshop. I did not change the scope of the question. I can confidently say this is not possible within Photoshop, including that tag is just noise.

@Mokubai posting an answer stating that it is not possible using Photoshop does not answer the question. It does not solve their problem. Note this specific line in the question: "(or in windows if not in photoshop)"

In the comments, I confirmed that the user did not necessarily require the solution to use Photoshop. I would not have suggested this edit had I not confirmed that. It was my mistake to assume that comments would have been visible to the suggested edit reviewer; in the future I'll be more clear about that in the edit message.

I think this is a short-sighted way of approaching this. The user is ultimately not trying to determine if this is possible in Photoshop, they are looking for a solution to an image recognition problem. Photoshop, as discovered, is completely irrelevant to the question. The user is asking the wrong question, my intent was to help correct that.

...and as I replied in chat, I left a mention of Photoshop in the question. The removal of the tag does not change the question. The comments clarify that the user is willing to accept answers outside of Photoshop.
