Feature-Preserving Flows: A Stochastic Differential Equation's View

Evolution equations have proven to be useful in tracking fine to coarse features in a single level curve and/or in an image. In this paper, we give a stochastic insight to a specific evolutionequation, namely the geometricheat equation, and subsequently use this insight to develop a class of featuredriven diffusions. A progressive smoothing along desired features of a level curve is aimed at overcoming effects of noisy environment during feature extraction and denoising applications.
