Abstract :
A method for image correction is proposed under illumination change. The intensity changes can be modelled as an additive factor and a multiplicative factor relating current image to reference image. The parameters are estimated based on maximum likelihood estimation. For motion compensation, the process of outlier detection is performed. The experimental results demonstrate that the proposed method is efficient and accurate.
