An Adaptive Short Time Beltrami Kernel forImage De-noising

Short time Beltrami kernel is a well known method forimage de-noising using diffusion on image manifold. In thispaper we propose an adaptive short time Beltrami. In theproposed method we adapt an effective parameter in Beltramialgorithm according to local variance of image. To evaluate theperformance of the proposed method, several comparativeexperiments are performed. The obtained results confirm theefficiency of the proposed method.
