I am looking for a programm, that compares screenshots from documentaries with a (very small) number (around 600) of source screenshots (from the footage they originate from). The differences between the source and the documentary screenhots my vary heavily, so I look for a tool that allows to assess rather weak levels of similarity.
I admit that I am not a coder, so would welcome a solution, as simple as possible. I could provide examples, if someone wants to help out (historiographical university project about footage from national socialism)
I am not looking for a duplicate finder.
