This paper introduces a spatial-temporal filter to eliminate stripe noise in infrared images.Detectors in the same column of the infrared focus plane array are read out by one readout circuit.The difference between voltage biases of the readout circuits results in strong stripe noise in infrared images.This paper proposes a method to estimate the voltage biases from the infrared images by using a spatial nonlinear filter based on the assumption of spatial correlation of infrared radiation.Meanwhile,the vari...
