How to judge image similarity？

[ssvicnent]

Hi, thank you very much for your work.
I have a question about how to use efficientloftr to determine if two images are similar?

Hi, a naive approach would be to use the number of matches as a measure of similarity. You could also explore other methods or combine it with image retrieval techniques.
