Abstract

The invention relates to an image fusion technique, in particular to an infrared intensity image and infrared polarization image enhancement and fusion method, which can solve the inherent problems of edge distortion and low contrast in conventional infrared fused images. The method is carried out according to the following steps that support value transform is respectively carried out on an infrared intensity image and an infrared polarization image, so that low-frequency images and support value sequence images are obtained; the top-hat transform of mathematical morphology is used for respectively extracting bright information and dark information; the bright information images and the dark information images are enhanced; the two last-layer low-frequency average images and the two enhanced images are fused, so that a low-frequency enhanced fused image is obtained; inverse support value transform is carried out on the low-frequency enhanced fused image and a support value sequence image fused by a maximum method, so that a final fused image is obtained, the contrast between the targets and the background in the fused image is enhanced, and edge distortion is little.

Description

technical field [0001] The invention relates to image fusion technology, in particular to an enhanced fusion method for infrared light intensity images and infrared polarization images. Background technique [0002] Infrared imaging technology has the characteristics of all-weather, passive work, and strong anti-drying, and is widely used in military and civilian fields. The traditional infrared imaging technology mainly uses the infrared radiation intensity of the object to image, and the infrared light intensity image is obtained. The rapid development of infrared light intensity imaging technology also promotes infrared smoke, infrared stealth and camouflage, infrared decoy bombs, and infrared interference. The development of infrared countermeasure technology such as machine guns has made the traditional infrared light intensity imaging technology face serious challenges. The newly emerging infrared polarization imaging is different from the original infrared light inte...
