Image similarity search, indexing and retreival

Hi CV Reddit, I need some help from you all. I'm trying to look through a social media dataset and I have to find either exact or slightly modified image that has been shared around in the dataset and then do some post analysis after that.


I could use some direction to finding a existing tool, algorithm or research paper that could help me find such images in my dataset.


Any suggestions/directions are appreciated.


Thank you.
