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 imageâ€¦ (More)

A new formulation for inhomogeneous image diffusion is presented in which the image is regarded as a surface in 3-space. The evolution of this surface under diffusion is analyzed by classical methodsâ€¦ (More)

Mean curvature diiusion is shown to be a position vector diiusion, tending to scalar diiusion as a at image region is approached, and providing noise removal by steepest descent surface minimization.â€¦ (More)

Most of the recent work on inhomogeneous diiusion in image ltering focuses on diiusing the isotope curve. We present a less familiar approach to the development of inhomogeneous diiusion algorithmsâ€¦ (More)
