This package contains matlab files for computing repeatability and matching score between two images [ref. performance evaluation papers].
http://www.robots.ox.ac.uk/~vgg/research/affine
km@robots.ox.ac.uk
Recompliling c_eoverlap.cxx and descdist.cxx might be necessary
matlab>>mex c_eoverlap.cxx;
matlab>>mex descdist.cxx;
To compute the repeatability score [ref. detector evaluation paper]:
[v_overlap,v_repeatability,v_nb_of_corespondences,matching_score,nb_of_matches]=repeatability('img1.haraff.sift','img2.haraff.sift','H1to2p','img1.ppm','img2.ppm',1);
v_overlap - overlap errors used for estimation of the repeatability.
v_repeatability - repeatability estimated for given overlap errors
v_nb_of_corespondences - number of corresponding regions for given overlap errors
matching_score - matching score for a given overlap error
nb_of_matches - number of correct matches for a given overlap error
To evaluate desciriptor performance on a pair of images [ref. descriptor evaluation paper]:
run repeatability to compute the correspondence matrix
[v_overlap,v_repeatability,v_nb_of_corespondences,matching_score,v_nb_of_matches,twi]=repeatability('img1.haraff.sift','img2.haraff.sift','H1to2p','img1.ppm','img2.ppm',0);
then run descperf to compute the matching score
[correct_match_nn, total_match_nn,correct_match_sim,total_match_sim,correct_match_rn,total_match_rn]=descperf('img1.haraff.sift','img2.haraff.sift','H1to2p','img1.ppm','img2.ppm',v_nb_of_corespondences(5),twi);
correct_match_nn - number of correct matches with nearest neighbour matching strategy
total_match_nn - total number of matches with nearest neighbour matching strategy
correct_match_sim - number of correct matches with threshold based matching strategy
total_match_sim - total number of matches with threshold based matching strategy
correct_match_rn - number of correct matches with nearest neighbour distance ratio matching strategy
total_match_rn - total number of matches with nearest neighbour distance ratio matching strategy
