A Multi-focus Image Fusion Based on Wavelet and Block-dividing

摘要

The traditional fusion rules of multi-focus image are largely centered on the fusion rule of high frequency coefficients, and those rules are all based on single pixel. Which leads to serious ringing effect, and reduces the visual effect of fusion image. The energy of an image is concentrated in the low frequency part after Wavelet Transform, and multi-focus image has the characteristic that the vast majority of adjacent pixels are either the clear area, or the blur area. Based on the above analysis, a new fusion method to multi-focus image is presented in this paper. The simulation results show that the proposed method is more feasible than common methods in processing multi-focus image.
