Based on non-subsampled contourlet transform,the original registered image is dealt with non-subsampled Contourlet decomposition and then with low-frequency component fusion by means of regional energy ratio weighting method.The high-frequency coefficients of the fused image are determined by combining average gradient with local energy.Experimental results show that the method may ensure the fused image to inherit more original detailed features.
