This paper focuses on the multi-focus image fusion based on wavelet transformation, making in-depth discussion and improvement on the existing algorithms from the aspect of the rules of multi-focus image fusion. Especially the parameter of the regional contrast is selected in the algorithm which can reflect better distinct features of the image frequency domain in the high-frequency coefficients fusion. And according to the fusion rule :" the part of the large regional contrast of wavelet high frequencies coefficients corresponding to the clear part of the image " , an improved algorithm is proposed for multi-focus image fusion based on wavelet transform regions contrast. Finally, Matlab is employed to simulation the algorithm.
This paper analyzes automatic image registration algorithm, and image features of radar and electronic chart, then, image registration algorithm based on Harris feature point are given, in which the methods are specially described. Wavelet transformation method on image feature should be considered. Moreover, simulate results of image fusion.
