COMBINATIONAL ALGORITHM FOR NONUNIFORMITY CORRECTION OF INFRARED FOCAL PLANE ARRAY
一种红外焦平面非均匀性组合校正算法

The cause of the target fade-out in the traditional neural network nonuniformity correction algorithms for infrared focal plane array(IRFPA)was studied.A new combinational algorithm for nonuniformity correction was proposed on the basis of analyzing the strengths and limitations of edge-directed NN scheme(ED-NN-NUC) and nonuniformity correction combining one-point calibration and NN-NUC.The new algorithm includes three modules which are pre-correction,rough correction and accurate correction.The real infrar...
