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.
