Abstract

A novel scheme for anisotropic diffusion driven by the image autocorrelation function is implemented. The diffusion tensor field is estimate by autocorrelation and computation from a scalar product of diffusion tensor and the image Hessian functions obtains an evolution equation. For a minimized spatial support for a hessian a set of filters are proposed. The filtering method performs favorable in many cases in particularly at low noise levels. A real time performance is easily achieved in a GPU implementation.
