An improved method for directional image smoothing based on structure tensors and vector field visualisation techniques.

Résumé

We propose an alternative diffusion technique, starting from a tensor-based method that can perform both isotropic and anisotropic smoothing using as directional information the eigenvectors of the image structures. The method employs two tensors, a structure and a diffusion tensor respectively, the novelty consisting in the manner in which we design the diffusion tensor. The developed method allows a fast implementation and a reduced number of time iterations, being discretized by a trace-based method. Testing is performed both on synthetic and real images, with quality measurements and remarks.
