摘要
在以往红外焦平面阵列的盲元检测方法的基础上,提出了一种基于像元噪声电压和改进的最大类间方差法(OTSU)的快速检测方法,该算法采用一次均匀背景的采集结果计算像元噪声电压,并利用最大类间方差和最小类内方差的算法原理计算并得出判定盲元的阈值。实验结果表明,文中方法在准确性和实时性方面有较大的提高。
A novel method for blind element inspection of IRFPA based on traditional methods of blind pixels detection is proposed. This ameliorated algorithm uses the data extracted from homogeneous background for one time to calculate the noise signals, and then finds the threshold for blind pixels detection according to conception of OTSU and minimum interclass variance. Experimental results indicate that this new method is capable of real-time blind pixels inspection with high accuracy and low complexity in comparison with traditional algorithms.
