According to the choice of fusion rules, a fusion algorithm based on non-subsampled Contourlet transform(NSCT)is proposed for infrared polarization and light intensity image fusion. Firstly, the NSCT is used to perform the multi-scale and multi-direction decomposition of the source images. Then the low frequency sub-band coefficients and high frequency sub-band coefficients of the fused images can be obtained by the fusion rules based on the local energy and regional characteristic of the target. The experimental results show that the local standard deviation increases by 3.42%, the local coarseness increases by 12.7% and the contrast increases by 9.67%, by comparing with the fusion rules of weighted average and maximum absolute value.
