Multi-Scale Image Registration Algorithm Based on Morphological Gradient

Image registration is a key step of image processing technology, which could be used for image processing including pattern recognition, image fusion, computer vision and other practical problems. In this paper, a new image registration algorithm is presented. First, morphological gradient is a method that gets the edge of image by using image edge detection. And then try experimenting with combination of Harris corner detection algorithm to get the multi-scale image registration algorithm.
