The SIFT algorithm-based two-generation identity card face comparison method has high tolerance to light, noise, micro perspective variation, and has high detection rates of partial object obstruction, can calculate positions and orientations only with more than three SIFT object features; and the ...
In this process a feature extraction algorithms such as SIFT and a Corner detection algorithm is used. SIFT provides good results when there are scale variations and rotations and when there are less rotations corner detection algorithms can perform better.M. S. Bhosale...
Aiming at improving the performance of scale invariant feature transform (SIFT) algorithm during the registration of optical and synthetic aperture radar (SAR) images, a new SIFT algorithm is proposed. Firstly, the nonlinear diffusion scale space of optical and SAR images is constructed by using non...
