I am matching 2 images by their features in openCV ( I've used SURF specially but I am going to compare all other methods too. Depending on match rate) I want to get similarity rate of 2 images e.g A image %85 similar to B image. how can I do it?

P.S: I am looking for good opencv svm tutorial since it is lack of documentation.

What you could try:

  • Match features from image A to image B
  • Eliminate false matches using the (Lowe) ratio test
  • Calculate the ratio between the "true" matches and the number of pairs of features

Also, you can see: measure similarity between two images

For OpenCV SVM tutorial, you have:
