An Advanced Algorithm of Multi-Focus Images Fusion Based on Wavelet Transform

Abstract:

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.
