WebIn computer vision, speeded up robust features (SURF) is a patented local feature detector and descriptor. It can be used for tasks such as object recognition, image registration, … SIFT is quite an involved algorithm. There are mainly four steps involved in the SIFT algorithm. We will see them one-by-one. 1. Scale-space peak selection: Potential location for finding features. 2. Keypoint Localization:Accurately locating the feature keypoints. 3. Orientation Assignment:Assigning orientation to … See more Key0points generated in the previous step produce a lot of keypoints. Some of them lie along an edge, or they don’t have enough contrast. In … See more At this point, each keypoint has a location, scale, orientation. Next is to compute a descriptor for the local image region about each keypoint that is highly distinctive and invariant as possible to variations such as changes in viewpoint … See more Now we have legitimate keypoints. They’ve been tested to be stable. We already know the scale at which the keypoint was detected (it’s the same as the scale of the blurred image). So we have scale invariance. The next … See more
