Mean Curvature Evolution and Surface Area Scaling in Image £ltering
Adel I. El-Fallah, Gary E. Ford · eScholarship (California Digital Library) · 1997
Representing the image as a surface, an inhomogeneous diffusion algorithm is developed, evolving the surface at a speed proportional to its mean curvature, reducing noise while preserving image structure. An adaptive scaling parameter increases the speed of the diffusion. The properties of a discrete algorithm are demonstrated experimentally
