Regularized coherence enhancing filtration

Abstract

The article deals with the nonlinear tensor diusion which yields a coherence im-provement. It is very appropriate for images with
ow-like structures. Two convolutions are used
in the construction of diusion tensor for such a model, see [10, 3]. In this paper we introduce the third supplemental convolution in order to enhance the diusion strategy.

First we briely present the classical coherence enhancing model and explain our modication. Then the discrete scheme and its analysis are provided. The core of the paper is constituted by
numerical experiments. Benets of the additional convolution are discussed and illustrated in the figures.
