Abstract

A new image registration method for infrared images and visible images is proposed in this paper. This method is a modified version of SIFT algorithm. Salient points of infrared images and visible images are extracted along edges of images. Each salient point is assigned a dominant direction which is the peak of orientation histogram of local image around it and a feature vector which is formed from the orientation histograms of sub-region around it. After salient points matching, RANSAC algorithm is used to eliminate wrong corresponding pairs. Experimental results show that this method has a good registration result for infrared images and visible images.
