| 摘 要： | 在分析IRFPA响应稳定性的基础上,针对现有的非均匀性校正方法的不足和实际工程需求,提出了一种自适应的基于场景主动运动控制的非均匀性校正方案.以传统的人工神经网络法(NN-NUC)为基础,针对其在实际应用中存在的不足进行了改进:加入了预校正环节降低固定图形噪声(FPN)、自适应的学习速率加快算法收敛速度、设置阈值识别场...

| Abstract: | On the basis of analyzing IRFPA response stability,an adaptive scene-based nonuniformity correction(NUC) scheme,which could actively control the movement of scene,was presented according to the disadvantages of existing NUC algorithms and requirements of engineering applications.Aiming at the shortcomings of the artificial neural network nonuniformity correction(NN-NUC) algorithm,an improved NN-NUC algorithm was presented by adding reserved NUC to reduce the fixed pattern noise(FPN),designing adaptive step ... |
