WebJan 1, 2024 · 4.1 Fast feature point detection. Extracting feature points is also an interesting part of the extracted image. The selection of general feature points includes boundary points, spots, and corner points, and these points not only contain a lot of information about the image, but also determine the attributes of the image. WebFirstly, Oriented FAST and Rotated BRIEF (ORB) feature points are extracted from the input image. Secondly, the feature points are then sorted in a descending order according to their response values. Then, the first five non-overlapping feature points are selected for the embedding by using Hamming window-based filtering method.
