I am building an event app and I would like to build a systems that allows to upload the event's images and match them with the event's participants (users have a profile pic and participate to the event on the app by clicking a button). Once the the images are matched they should be sent to each user accordingly.
I found a lot of tutorials or threads about image "category" recognition but I couldn't find anything quiet similar to what I am looking to achieve - does anyone have any idea?
