Script to recognize similarity between images

Question

Good afternoon Everybody, all right?

I am starting my studies in Python together with Opencv, and I want to perform the reading of images and display the degree of similarity between them.

Ex: I have a database with several images, I will give the script another image from another database, and it will have to look for the most similar image in the current database.

It is possible to carry out such action?

NOTE: I found some tips in some forums , however, most were comparing only 2 images already delivered to the script, and only returned True or False if it was similar, and not its degree, or the respective image that is similar

Answer 1

Similar means how similar images are, this is image processing + pattern recognition, you’re searching for features that are similar between two or more images. I suggest searching for such terms on google, you can use a SIFT + KNN, for example, to compare them.

In this question, he does this with SIFT, this algorithm you find in Python:
