Description

I tried running the example SURF_Homography.cpp in http://docs.opencv.org/doc/tutorials/features2d/feature_homography/feature_homography.html with OpenCV 2.4.2 and found out that the result is invalid. (See the attached screenshot. ) I switched from SURF to SIFT and the result turned out to be valid again. Also, when I use OpenCV 2.3.1 with SURF, the result is valid as well. Therefore it is very likely that there is too drastic a change from 2.3.1 to 2.4.2 in SURF, which causes SURF to underperform.
