基于反中值滤波的红外焦平面自适应非均匀性校正方法

Adaptive Nonuniformity Correction Based on Inverted Median Filtering of Infrared Focal Plane

分析了红外焦平面阵列非均匀性的噪声特性,提出了一种用反中值滤波为核心的红外焦平面自适应校正的方法。针对实际的图像进行了实验,实验证明该方法在校正效果、收敛速度、对静止目标保持能力及可硬件化等方面都有较好的表现。

Based on the analysis of the nonuniformity noise characteristics in infrared focal plane arrays, an adaptive method with the core of inverted median filtering for nonuniformity correction in infrared focal plane arrays is presented in this paper. The experiments with real image are made and the results show that this method has many advantages in the correction effectiveness, convergence rate, hold facility for static target and the hardwired capability.
