Embodiment Construction
[0053] The invention provides an R-SIFT-based hardware Trojan image registration method, storage medium and equipment. Firstly, different scale spaces are constructed for two images with registration, and then key features are obtained by detecting extreme points in different scale spaces. point, find the direction information of the feature point through the neighborhood relationship of the feature point. At this time, the feature point contains three pieces of information: position, scale, and direction. The feature descriptor of the feature point is formed by the information contained in the feature point, and the feature description vector is obtained through normalization. The matching point pairs are obtained on the two images by matching the description vectors of the feature points. Finally, the redundant points are screened out through the RANSAC algorithm to obtain the final matching result.
