Image registration by blur and rotation invariants of Legendre moments
Hui Zhang, Xiubing Dai, Huazhong Shu · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2010
In this paper, we introduce a new algorithm to register images with rotation and image blurring. The characteristic of this approach is that a set of Legendre moment invariants are used to establish the correspondence of corner points between the reference image and the distorted image, after these points are extracted by Harris corner detector. Transformation parameters can be estimated from those matched points.
