Abstract:

This paper described a color multifocus image fusion algorithm based on discrete-wavelet frame transform. The intensity component of each multifocus image was decomposed by discrete-wavelet frame transform. According to the discrete wavelet frame transform coefficients, the clarity measure of each pixel in each multifocus image was calculated. The fusion process was performed by selecting the clearest pixels in the multifocus images. Experiments show that the proposed algorithm works well in color multifocus image fusion.
