一种新的基于场景的红外焦平面阵列非均匀性校正算法

A New Scene-based Nonuniformity Correction Algorithm in IRFPA

设计了基于小波变换去噪、序列图像配准、正交最小二乘拟合的基于场景的非均匀性校正算法 ,该算法不仅能适应红外焦平面阵列非 (IRFPA)均匀性随时间和环境变化而发生缓慢变化的情况 ,而且对一般基于场景分析的校正算法中形成的校正虚像也有很好的抑制作用

Based on the application of the wavelet filter,video sequences and registration, orthogonal least squares, a new adaptive nonuniformity correction technique is discussed. With the scene estimates,and the corresponding observed values through a given detector,a orthogonal curve-fitting procedure is used to estimate the individual detector offset and gain coefficients .Its efficiency and superiority are clarified by simulation.
