An overview is given of a regularized model of the PM diffusion equation for image segmentation. First, the hypothesis of well-posedness in the discrete space and the stability conditions is presented. Second, two methods are shown for automatic setting of the gradient threshold k, which is changed for each iteration of the partial differential equation (PDE) integration steps. Third, implementation of experimental segmentations for noise reduction of generic digital images and for segmentation of microcalcifications on X-ray biomedical changes is outlined.
