Abstract: In this paper, the high-frequency and low-frequency information were considered separately, and they both have their own fusion rules. First we use discrete wavelet transform to get high frequency coefficients part, and we use non-subsampled contourlet transform to obtain low and high frequency parts to get an initial fusion image, then a second fusion with the result of discrete wavelet transform. Experimental results show that compared with the several excellent algorithms, this algorithm shows better visual effects and shorter running time.
