A New Scene-based Nonuniformity Correction Algorithm in IRFPA

Bai Liping,Yin Shimin,Liu ShangqianDepartment of Technical Physics, Xidian University, Xi′an 710071  
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.
