A shape-based template matching method of image auto-splicing. Extract image feature points as corner points, using the normalized gradient of their pre-match template. The shape of the template and then use the template in the four directions within the image edge point and the shortest distance between the template border statistics, access to the template image of the structure of eigenvectors of the feature points in order to achieve the exact match. Experimental results show that the algorithm has good practical value.
