The invention discloses a
hardware Trojan horse
image registration method based on RSIFT, a storage medium and equipment, and the method comprises the steps: carrying out the
Gaussian filtering and down-sampling of an input image, and constructing a multi-
scale space; detecting an extreme point of the image in the constructed multi-
scale space; assigning values to the directions of the obtained extreme points to obtain position, scale and
direction information of the corresponding points, and generating feature descriptors; preliminarily generating a pre-matching
point pair by using the generated
feature descriptor and a distance matching method, and representing the pre-matching
point pair by using a matching matrix C; and after the pre-matching matrix C is determined, performing correction by using an RANSAC
algorithm, removing redundant matching points, and completing
image registration. According to the invention, the problem of affine transformation in
image registration is effectively solved, interference caused by
noise points can be avoided more flexibly, and the stability and accuracy of the image registration method are further improved.
