Structure tensor adaptive total variation for image restoration
Turkish Journal of Electrical Engineering and Computer Sciences, 2019 Image denoising and restoration is one of the basic requirements in many digital image processing systems. Variational regularization methods are widely used for removing noise without destroying edges that are important visual cues.

Adaptive mesh reconstruction: Total Variation Bound
, 2009 We consider 3-point numerical schemes for scalar Conservation Laws, that are oscillatory either to their dispersive or anti-diffusive nature. Oscillations are responsible for the increase of the Total Variation (TV); a bound on which is crucial for the ...

On the role of total variation in compressed sensing
, 2015 This paper considers the problem of recovering a one or two dimensional discrete signal which is approximately sparse in its discrete gradient from an incomplete subset of its discrete Fourier coefficients which have been corrupted with noise.
