WebAfter the SIFT features were computed, they were clustered using K-Means. The vocabulary size used was 200, which was also tuned using the validation set (see Results section). After the vocabulary was computed, the bag of SIFT features for each image were found using the Matlab function get_bags_of_sift(), shown below: WebThe second stage in the SIFT algorithm refines the location of these feature points to sub-pixel accuracy whilst simultaneously removing any poor features. The sub-pixel localization proceeds by fitting a Taylor expansion to fit a 3D quadratic surface (in x,y, and σ) to the local area to interpolate the maxima or minima.
