摘      要：A novel multi-focus polychromatic image fusion algorithm based on filtering in the frequency domain using fast Fourier transform(FFT) and synthesis in the space domain(FFDSSD) is presented in this ***,the original multi-focus images are transformed into their frequency data by FFT for easy and accurate clarity *** a Gaussian low-pass filter is used to filter the high frequency information corresponding to the image *** an inverse FFT,the filtered images are *** deviation between the filtered images and the original ones,representing the clarity of the image,is used to select the pixels from the multi-focus images to reconstruct a completely focused *** operations in space domain preserve the original information as much as possible and are relatively insensitive to misregistration scenarios with respect to transform domain *** polychromatic noise is well considered and successfully avoided while the information in different chromatic channels is preserved.A natural,nice-looking fused microscopic image for human visual evaluations is obtained in a dedicated *** experimental results indicate that the proposed algorithm has a good performance in objective quality metrics and runtime efficiency.
