摘要
经过参考辐射源的非均匀性校正算法进行校正的红外图像因受到各种因素的影响,质量逐渐下降,出现类似细胞状和块状斑纹的现象,提出基于统计红外图像噪声均匀区域的方法,改善图像质量。实验结果表明,红外图像质量有明显改善。
When infrared focal plane arrays （IRFPA） are running for quite a long period, the infrared image was corrected by the algorithm of non-uniformity correction with infrared emitting reference, because of various reasons, it will be degraded gradually, cell-like and blocked flecks will be brought. Just based on this kind of phenomena, a method by way of making statistical analyses of the noise＇s gray of infrared image in gray-uniform zones, is put forward in this paper. And it is proved by the experimental results that the infrared image＇s quality was improved obviously.
