A SAR/Infrared Image Fusion Method Based on NSCT and PCNN

In order to improve the quality of the fusion image between SAR image and infrared image, a novel SAR/infrared image fusion method based on non-subsampled contourlet transform (NSCT) and pulse coupled neural network (PCNN) is proposed. Firstly, this method decomposes the SAR image and infrared image respectively via NSCT. Then PCNN is used as the fusion rule of our method. Finally, the fusion image is obtained by taking the inverse NSCT transform. The results indicate that, compared with other fusion methods, higher resolution fusion image with rich information and strong contrast can be get by the method proposed in this paper.
