A novel restoration method for X-ray images with quantum mottles is proposed by considering the physical formation process of X-ray images. More specifically, as a restoration method for quantum mottles, a digital filter of the stochastic type considering the property of quantum mottles with varying variance is derived on the basis of the Bayes theorem matched to recursive image processing. In order to confirm the effectiveness of the proposed method, it is applied to an actual medical image.>
