I like this. I'm thinking it could be done in the following way:

• apply a state of the art and fast face detector and get face crops on a subset of the images
• let the user give a name to each face crop, for example "person_2"
• then user can use rclip "person_2" + <other images of person 2 if they were found in previous rclip iterations>"

what do you think?

or do you want to use CLIP only (it can be done this way too, but I think getting the crops would work better especially in photos where there's more people)

@rebelzion, thank you for the suggestion. I was thinking in a similar direction and definitely not married to CLIP :)
