Dynamic threshold image processing
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.

During the thresholding process, individual pixels in an image are marked as "object" pixels if their value is greater than some threshold value (assuming an object to be brighter than the background) and as "background" pixels otherwise. This convention is known as threshold above.Variants include threshold below, which is opposite of …
WebGlobal image threshold using Otsu's method Syntax level = graythresh(I) [level EM] = graythresh(I) Description level = graythresh(I) computes a global threshold (level) that can be used to convert an intensity image to a binary image with im2bw. level is a normalized intensity value that lies in the range [0, 1].
