 Due to the low contrast, lack of details and difficulties to distinguish target from background in traditional infrared(IR) imaging systems, the detection and recognition probability of camouflage infrared target is relatively low. The polarization image represents the polarization properties of the target. By the fusion of infrared polarization image and infrared image, the infrared target can be enhanced effectively and have a better visual character. In this paper, an infrared image fusion method using non-sampling Shearlets transform (NSST) and regional saliency analysis was proposed. Firstly, the infrared image was decomposed into several sub frequency bands by NSST. Then in the frequency domain the fusion rules were determined by regional saliency analysis. At last, final fused image was obtained by inverse NSST. Middle wave and long wave infrared experiments were done to verify the effectiveness of the presented method. Compared with other image fusion algorithms, both the subjective and objective evaluation results illustrate that the proposed approach could obtain better infrared fused images with less noise, higher contrast and larger information entropy and more mutual information. It has a good application in detection and recognition for infrared targets.
