SIFT (The Four Moves) Hapgood
Webreduces the computational time of SIFT feature detector algorithm for detecting the features in the image and increases the feature matching capability of features detected … 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 both cases, they are not as useful as features. So we get rid of them. The approach is … 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 … 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 … See more shantyboat living
