Research of multi-focus image fusion algorithm based on Gabor filter bank

Due to the unsatisfactory effects of those commonly-used multi-source focus image fusion algorithms, this paper proposes and designs a multi-focus image fusion algorithm based on Gabor filter bank with its process of implementation, using Gabor transformation and Gabor filter bank theory. By doing four multi-source focus images fusion experiments in Matlab and evaluating fused images subjectively and objectively, the results suggest that the multi-focus image fusion algorithm based on Gabor filter bank presents maximum mutual information, smaller distorted values, higher Q^ab/f values and better effects of image fusion.
