WebA-SIFT has better effect relative to SIFT in affine transform. So far, most improvement to SIFT emphasizes the representation and dimension reduction of feature vector, and few works considers the selection of feature. It is shown in that the fixed threshold, used in classic SIFT to exclude instable key points, cannot fit to all kinds of image.
