Research on Image Automatic Registration Based on Heterogeneous Features

The image registration based on the features of the image is a major research direction.The points feature is used in traditional registration methods,but the lines and other basic features are ignored. So,an image auto registration method based on natural heterogeneous features is given out. First, the feature points are detected using Harris feature detector and the feature line segments are detected using Hough transfer, then the one to one matching points and lines could be obtained through rough match, then the points feature and the parameters of lines is used to match refinely, finally, the image registration could be achieved through the homography matrix calculated by matching corner points and the parameters of line segments.
