How to find and share duplicate photos?

Question

Images

For wallpapers on my phone, I prefer to download full instagrams of beautiful girls. The problem with this stupid fashion is to fill one photo with two identical ones. This is of course due to Instagram and its old format of exclusively square photos. Instead of posting a good vertical photo, users are forced to fill this square either with a photo with white margins around the edges, or duplicate the same photo side by side in a square.
I want to
1. Automatically identify photos that do not contain a person (all kinds of manicures, wine, candles and other paraphernalia of a female Instagram) and delete them (for example, by face recognition and preferably a human figure in general)
2. On photos where there is a person, automatically detect the presence of white vertical fields, or duplication of the same photo (that is, the presence of a vertical border line) and automatically separate the photo along the line (or crop the side white fields) and save after processing.
Is there a recipe for this? Batch processing in photoshop, acdsee or somewhere else?

At least open a startup - the supply of guaranteed beautiful instaphotos for $ 1 / month ...
In general, the problem is not worth such a number of complex processes (recognition, etc.). It is easier to periodically spend a few minutes on manual selection.
