چکیده
We study a nonlocal version of the total variation-based model with L1 fidelity for image denoising, where regularizing term is replaced fractional s-total variation. discuss regularity level sets and uniqueness solutions, both high low values parameter. analyse in detail case binary data given by characteristic functions convex sets.

Hyperspectral Image Denoising with Cubic Total Variation Model
Image noise is generated unavoidably in the hyperspectral image acquision process and has a negative effect on subsequent image analysis. Therefore, it is necessary to perform image denoising for hyperspectral images. This paper proposes a cubic total variation (CTV) model by combining the 2-D total variation model for spatial domain with the 1-D total variation model for spectral domain, and t...

متن کاملExtensions to Total Variation Denoising
The Total Variation denoising method, proposed by Rudin, Osher and Fatermi, 92, is a PDE-based algorithm for edge-preserving noise removal. The images resulting from its application are usually piecewise constant, possibly with a staircase eeect at smooth transitions and may contain signiicantly less ne details than the original non-degraded image. In this paper we present some extensions to th...
متن کاملImage Denoising Using Llt Model and Iterated Total Variation Refinement
Abstract. Developing a variational model that is capable of restoring both smooth (no edges) and non-smooth (with edges) images is still a valid challenge in the image processing. In this paper, we present two methods for image denoising problems based on the use of the LLT model (see [14]) and iterated total variation refinement. The idea of our methods is, first make use of the LLT model to g...
متن کاملDenoising of image gradients and total generalized variation denoising
We revisit total variation denoising and study an augmented model where we assume that an estimate of the image gradient is available. We show that this increases the image reconstruction quality and derive that the resulting model resembles the total generalized variation denoising method, thus providing a new motivation for this model. Further, we propose to use a constraint denoising model a...
