The comparative efficiency of Wavelet filters for multi-focus color image fusion is presented in this paper. Our experiment purposes are study and examine the suitable mother wavelets for using in multi-focus color image fusion. In fusion process, we use HSI color model and the fusing technique based on Stationary Wavelet Transform with Extended Spatial Frequency Measurement method. In our experiments, we investigate the effect of applying different types of wavelet filters belonging to orthogonal and biorthogonal wavelets with different orders. The wavelet filter used are Daubichies4, 8, 10, 12, 14, 16, 18 and Biorthogonal2.2, 2.4, 2.6, 2.8, 3.1, 3.3, 3.5, 3.7, 3.9, 4.4, 5.5, and 6.8. The fused image quality assessment is measured using Peak Signal to Noise Ratio. The result indicated that Biorthogonal 3.3 and 3.5 are proper choices for multi-focus color image fusion.
