IR blind pixels detection algorithm based on adjustable threshold window

提出了一种基于窗口阈值可调整的红外盲元检测算法。该算法将一帧图像按窗口大小进行分割,通过调节窗口内阈值,计算窗口内的均值和标准差之间的大小关系,达到精确判断盲元的目的。试验结果表明,该算法盲元定位准确,盲元检测率高,能大幅提升红外图像质量。

An infrared blind pixels detection algorithm based on adjustable threshold window is presented. Through adjusting the window threshold,the magnitude between symmetrical value and standard difference is calculated,which can estimate the blind pixels accurately. The experimental results show that this algorithm finds the blind pixels accu-rately and detects the blind pixels very well,so it can improve the infrared image quality greatly.
