WebVLFeat implements a fast dense version of SIFT, called vl_dsift. The function is roughly equivalent to running SIFT on a dense gird of locations at a fixed scale and orientation. This type of feature descriptors is often uses for object categorization. Dense SIFT as a faster SIFT The main advantage of using vl_dsift over vl_sift is speed.

http://robwhess.github.io/opensift/ WebJun 9, 2012 · The Sorting Intolerant from Tolerant (SIFT) algorithm predicts the effect of coding variants on protein function. It was first introduced in 2001, with a corresponding website that provides users with predictions on their variants. Since its release, SIFT has become one of the standard tools for characterizing missense variation. WebII. Áp dụng SIFT cho bài toán phân loại. Để khởi tạo đối tượng SIFT trong OpenCV ta sử dụng lệnh: sift = cv2.xfeatures2d.SIFT_create () Tiếp theo chúng ta sẽ trích xuất đặc trưng qua SIFT hoặc có thể SUFT, HOG.
