摘要:
由于红外焦平面阵列成像存在盲元等一系列问题,为了减少盲元对红外图像的干扰,本文提出一种基于滑动窗口的红外焦平面阵列盲元检测算法。对像元进行加窗并计算其中的均值中值以及一级梯度等数值,再进行加权计算并设定阈值与原像元对比进行盲元检测,最后使用局部中值滤波算法进行盲元补偿。仿真结果表明此种方法可以有效地检测盲元,拥有比较好的盲元补偿结果,有效地改善了红外焦平面阵列成像质量。
Abstract:
A method for blind-pixel detection of infrared focal plane array (IRFPA) based on sliding window has been proposed in this paper to reduce the interference of blind pixels in infrared images. First, we set a selected pixel size to add the window and estimate the mean and median values as well as the first-order gradient. Next, the weighting calculation is performed, and the threshold is set to compare with the original pixel for blind pixel detection. Finally, the local median filtering algorithm is used to compensate for the blind elements. The proposed method can effectively detect the blind pixels with the help of simulation and shows a reasonable result for blind pixel compensation and thus can effectively improve the imaging quality of the IRFPA.
