WebNov 12, 2012 · You extract SIFT descriptors from a large number of images, similar to those you wish classify using bag-of-features. (Ideally this should be a separate set of images, but in practice people often just get features from their training image set.) Then you run k-means clustering on this large set of SIFT descriptors to partition it into 200 (or ...

WebMay 16, 2016 · 1. The features are extracted from the key points. In SIFT case they are blob like structures. In other words the vl_sift function looks for the key point and extracts a 128 dimensional descriptor from EACH of the key points. You have various dimensions (128*1 or 128*2 etc...) because in one image vl_sift finds one key point in the other one it ... WebApr 10, 2024 · Matlab is internally consistent in the way it indexes matrices and cell arrays. Mechanically, does the same thing to both data types, but there is one critical difference.
