WebApr 24, 2024 · Scale Invariant Feature Transform is an algorithm in a computer vision to detect and describe the local feature in the digital image. SIFT algorithm is invariant to scaling, noise and rotation transformation. This system is commonly used for detection of the manipulation done in the digital image (image forgery). REFERENCES. WebSee highlighted features corresponding to the object. Features: You can change any parameters at runtime, make it easier to test feature detectors and descriptors without always recompiling. Detectors/descriptors supported (from OpenCV): BRIEF, Dense, FAST, GoodFeaturesToTrack, MSER, ORB, SIFT, STAR, SURF, FREAK and BRISK.
