An Image Edge Based Algorithm for Multisensor Image Registration
一种基于边缘的图像配准方法

Image registration is an very important technology in nmltisensor image fusion. There is little correlation among multisensor images, especially images with different bands. It is very difficult to matching these images. Among some images which can be described in affine model, edge is a very obvious character. In this article, wavelet analysis is used to extract image edge, then correlative deviation is calculated. When correlative deviation reaches the minor, the image registration parameters are obtained. The processing of SPOT and TM images demonstrates the efficacy of the proposed method.
