Abstract : The non-linear diffusion of Perona and Malik method is applied to a contour. Unlike most of the contour diffusions techniques, the contour is described by the angle variation, and the non-linear diffusion procedure is applied to the contour turning angle. Perona and Malik model determines how strong diffusion will act on the original function, and depends of a factor K, estimated automatically. In areas with spatial concentration of strong changes of the angle this factor is also adjusted to reduce the contour small perturbations and noise effect.
