This program allows to compare possible image duplicates from a CSV (you can use python script https://git.kmpr.at/kamp/SimilarImages to find them and generate the CSV file) or an API (https://git.kmpr.at/kamp/DuplicateAPI which can be fed by the same python script) and delete one of the duplicates.

Keyboard Control: [1] - delete first possible duplicate [2] - delete second possible duplicate [0] or [K] - mark images as non-duplicates [D] delete most probably worst indicated duplicate (which has the bold delete button)
