Next, we tested our algorithm on image registration in panorama, using 15 image sequences captured by the phone pilot system. Fig. 6(b) shows the true positive rate for correctly estimating the homography geometry, which results in the correct
stitching of the panoramas. Results based on region categorization by filtering out “unimportant” subregions have much higher true positive rates, partlydue to the fact that our testing dataset includes many pictures with dense texture or noisy regions.
