Title Image processing and fusion technique based on polarization information
Abstract Today, the battlefield information is applied more and more widely, requirements of perceptual information higher and higher, On the one hand, the amount of information from infrared image has been unable to meet the demand, on the other hand, because of the lack of infrared imaging principle, and polarized infrared fusion image can better to improve the shortcomings。
This topic through the infrared thermal imager and polarizer captured in the polarization angle of 0 DEG, three cases of 60 and 120 degrees corresponding to the infrared image, according to the corresponding formula calculation to get x1, x2 and x3 image, has been further polarization degree image and polarization angle image。 Finally, on x1 image, the degree of polarization and the polarization angle image were polarized infrared image fusion, and get the high quality of infrared polarization image。 Experimental results show that the polarization imaging and fusion technology can better avoid background scattered light to the imaging target produce effect and improve the contrast of the background and target, so that high resolution image, effectively improve the recognition rate of the object being detected
Keywords: image processing infrared polarization imaging image fusion stokes vector wavelet transform
