issue solved. Will the number of images makes the model more clear? ]]>

The confidence of each match can be deduced by the descriptors distance. More elaborate mechanisms are the ratio test, fitting a transformation between images and removing outliers via ransac or best buddies similarity.

]]>in the official it says x and y run from [-r, r] I did not get it? how to calculate the r? ]]>

that’s a very nice explanation.

one thing that is missing: “the accuracy”. matching descriptors is great, but how can I tell the confidence of each match? ]]>

Can you explain how the variance between two pairs of binary vectors is calculated ?
