Abstract
Image registration is the premise of image fusion and other image processing applications. It is also the hot spot in the image processing. This paper describes image registration based on characteristic points under MATLAB environment. Firstly, we represent the methods of image registration, and then select the matching points using human-computer interaction methods provide by MATLAB between the reference image and the floating. Comparative analysis of different interpolation techniques for alignment are offered. Meanwhile, we determine the better methods to assign gray values, then make use of these control points to confirm geometric transformations. Finally, we perform the geometric transformation in connection with the input images to obtain registration results. Simulation results show that the method is easy to implement and we can obtain effective registration results.关键词
