1) Invalid scanning pixel
无效扫描像元
2) non-effective pixel
无效像元
1.
A method of IRFPA non-effective pixel discrimination based on NETD and gray minimum variance is put forward.
提出了一种基于噪声等效温差(NETD)和灰度最小方差的红外焦平面阵列无效像元检测方法。
2.
A new approach of IRFPA non-effective pixel discrimination based on pixel′s two kinds of characteristic histogram decomposition was presented.
为有效地判别和剔除红外焦平面阵列(IRFPA)的无效像元,本文在分析了IRFPA有效像元响应模型的基础上,指出在均匀输入时IRFPA有效像元输出值的均值差(DOM)和标准差 (STD)特征的分布具有正态性,通过采用自适应投影匹配分解法对特征直方图进行高斯分解,进而估计出有效像元DOM和STD特征的分布区间,从而得到了判别无效像元的分类准则。
