From left to right:some image regions and corresponding scores (from the base classifier) at iterations 1, 3, 6, and 9.
(a) for each iteration, the regions at ranks 1, 3, 5 and their scores are shown. For clarity, we list the region scores and region weights underneath each image.
(b,c): the scores of the same set of regions through iterations. The regions in (b) are the ones that are ranked 1, 3, 5 at the first iteration. In (c) are the regions that are ranked 1, 3, 5 after convergence.
