A New Adaptive Nonuniformity Correction Algorithm for IR Focal Plane Arrays

JIANG Guang, LIU Shang-qian (School of Technical Physics, Xidian University, Xi'an 710071, China)  
The non-uniformity problem is widely existed in IR focal plane arrays (IRFPA). This non-uniformity will change slowly with time and environment conditions. The common disposable correction algorithm cannot suit this change. At the same time, since the diversity in image scene, the existing statistic correction algorithm still existed some adaptability problems. Based on the optical flow technique in image motion analysis, a new continuous correction algorithm based on scene is proposed in the paper. The algorithm has a better adaptive performance.
