Global Total Variation Minimization [PDF]
SIAM Journal on Numerical Analysis, 1999 Summary: The minimization of the total variation is an important tool of image processing. A lot of authors have addressed the problem and developed algorithms for image denoising. In this paper we present an alternative approach of the total variation minimization problem.

Total roto-translational variation [PDF]
Numerische Mathematik, 2019 We consider curvature depending variational models for image regularization, such as Euler's elastica. These models are known to provide strong priors for the continuity of edges and hence have important applications in shape-and image processing. We consider a lifted convex representation of these models in the roto-translation space: In this space ...

Forward-Looking Super-Resolution Imaging for Sea-Surface Target with Multi-Prior Bayesian Method
Remote Sensing, 2021 Traditional forward-looking super-resolution methods mainly concentrate on enhancing the resolution with ground clutter or no clutter scenes. However, sea clutter exists in the sea-surface target imaging, as well as ground clutter when the imaging scene ...

On the total variation of the Jacobian
Journal of Functional Analysis, 2004 Let \(\Omega\) be an open subset of \({\mathbb R}^2\), and \(u=(u^1,u^2)\in L^\infty_{\text{ loc}}(\Omega;{\mathbb R}^2)\cap W^{1,p}(\Omega;{\mathbb R}^2)\) for some \(p>1\). In the paper, a comparison is carried out among the classical Jacobian determinant \(\det Du\) defined a.e. in \(\Omega\), the distributional Jacobian determinant \(\text{ Det} Du\

A new inequality for the Riemann-Stieltjes integrals driven by irregular signals in Banach spaces
Journal of Inequalities and Applications, 2018 We prove an inequality of the Loéve-Young type for the Riemann-Stieltjes integrals driven by irregular signals attaining their values in Banach spaces, and, as a result, we derive a new theorem on the existence of the Riemann-Stieltjes integrals driven ...

Dead-Time Compensation for the First-Order Dead-Time Processes: Towards a Broader Overview
Mathematics, 2021 The article reviews the results of a number of recent papers dealing with the revision of the simplest approaches to the control of first-order time-delayed systems.

Journal of Mathematical Imaging and Vision, 2017 Discretization schemes commonly used for total variation regularization lead to images that are difficult to interpolate, which is a real issue for applications requiring subpixel accuracy and aliasing control. In the present work, we reconciliate total variation with Shannon interpolation and study a Fourier-based estimate that behaves much better in ...

Semisoft Generalized Total Variation Minimization for Image Reconstruction in Computed Tomography
IEEE Access, 2017 The generalized l1 greedy algorithm was recently proposed and shown to outperform the standard reweighted l1-minimization and l1-greedy algorithms for image reconstruction in computed tomography (CT).

Total Variation Isoperimetric Profiles [PDF]
SIAM Journal on Applied Algebra and Geometry, 2019 Applications such as political redistricting demand quantitative measures of geometric compactness to distinguish between simple and contorted shapes. While the isoperimetric quotient, or ratio of area to perimeter squared, is commonly used in practice, it is sensitive to noisy data and irrelevant geographic features like coastline.
