Multi-spectral remote image registration based on SIFT
Zhiqian Yi, Cheng Zhiguo, Xingrui Yang · Electronics Letters · 2008
The number of incorrect matches of SIFT keypoints will sharply increase when the SIFT-based registration algorithm is adopted for pairs of multi-spectral remote images, owing to the significant difference in the image intensity between multi-spectral images. Scale restriction criteria for keypoint matching are proposed, and experimental results demonstrate that it will greatly improve match performance.
