WebSep 22, 2024 · The proposed dense SIFT clustering performance was evaluated on four different machine learning algorithms and achieved a high rate of recognition accuracy in all classes. In the experimental results, K-NN exhibits the proposed architecture’s effectiveness with an accuracy rate of 91.8% for the MUG dataset, 89% for SVM, 87.6% for Naive Bayes, … 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 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 … 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
