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. can i use git for word documents

In digital image processing, thresholding is the simplest method of segmenting images. From a grayscale image, thresholding can be used to create binary images. WebBloom is a real world light phenomena that can greatly add to the perceived realism of a rendered image at a moderate render performance cost. Bloom can be seen by the naked eye when looking at very bright objects that are on a much darker background.
