WebApr 2, 2013 · The function call flannmatcher.match (queryDescriptors, matches); does the matching. All you have to do is use the indices in the vector matches. – Sammy Apr 18, 2011 at 12:21 Sorry for the late reply, thanks, I finally understood the index thing. Anyway, I am trying to reduce false positives can you suggest any complex measures of similarity. WebBuild a FLANN index from the concatenated matrix. Compute descriptors for the query image. Run KNN search over the FLANN index to find top 20 or less best matching image. K is set as 20. Filter out all the inadequate matches computed in the previous step. (How??) I have successfully done steps number 1 to 5.
