WebA brute-force matcher is a descriptor matcher that compares two sets of keypoint descriptors and generates a result that is a list of matches. It is called brute-force because little optimization is involved in the algorithm. For each keypoint descriptor in the first set, the matcher makes comparisons to every keypoint descriptor in the second set. http://www.uwenku.com/question/p-wojiwhxk-bdx.html
