Multi-Focus Image Fusion Based on Shearlet Transform Using Genetic Algorithm

In this paper, a novel method for multi focus image fusion based on shearlet transform using genetic algorithm is proposed. Proposed method consist of three basic steps. First of all, ST is firstly applied to source images separately. Then, fusion rate of source images is determined using GA and source images are fused according to the rate of fusion determined by GA. Lastly, fused image is obtained applying inverse ST to fused image of ST. Fused image is evaluated according to quality metrics such as variance, spatial frequency. Experimental results show that the proposed method is more effectively than traditional method. Together with GA and ST for multi focus image fusion is firstly presented in literature.
