中波红外偏振成像图像处理及评价

介绍了光波斯托克斯矢量各分量的解算方法,给出了多种偏振图像融合的初步结果,对融合的偏振图像进行了定性分析和定量评价.研究表明,偏振图像的融合能产生多种图像融合结果,为图像的显示提供了多种选择.融合后的偏振图像细节更加清楚,边缘更突出,立体感更强.与原始红外图像比较,中波红外偏振图像灰度均值提高35%,灰度标准差提高61%,梯度提高255%.处理后的偏振图像和原始的红外图像比较说明了偏振成像能明显提高目标和背景之间的对比度.

Images Processing and Evaluation of Middle Wave Infrared Polarization Imaging System

The methods of computing of Stokes parameters,the initial polarimetric images and the corresponding qualitative and quantitative evaluations of MWIR polarization imaging system are presented in this paper. There are several results of fusion of polarimetric image,the results provide with multiple choices to the displaying of image. The polarimetric images of fusion are clearer in profile,more protuberant in edge and better in stereo sense than the original images of MWIR polarization. For the polarimetric i...
