Kernel Estimation Using Total Variation Guided GAN for Image Super-Resolution [PDF]

open access: yesSensors, 2023
Various super-resolution (SR) kernels in the degradation model deteriorate the performance of the SR algorithms, showing unpleasant artifacts in the output images. Hence, SR kernel estimation has been studied to improve the SR performance in several ways

CMOS Fixed Pattern Noise Elimination Based on Sparse Unidirectional Hybrid Total Variation [PDF]

open access: yesSensors, 2020
With the improvement of semiconductor technology, the performance of CMOS Image Sensor has been greatly improved, reaching the same level as that of CCD in dark current, linearity and readout noise. However, due to the production process, CMOS has higher

Directional Total Variation [PDF]

open access: yesIEEE Signal Processing Letters, 2012
This paper introduces a “directional total variation” (TV) where the gradients are weighted depending on their direction. The introduced directional TV has increased (and tunable) sensitivity to variations at a selected direction. In order to demonstrate the utility of the directional TV, we consider an image denoising formulation.

Total Variation as a Local Filter [PDF]

open access: yesSIAM Journal on Imaging Sciences, 2011
In the Rudin-Osher-Fatemi (ROF) image denoising model, total variation (TV) is used as a global regularization term. However, as we observe, the local interactions induced by TV do not propagate much at long distances in practice, so that the ROF model is not far from being a local filter.

Active Disturbance Rejection Control for Wind Turbine Fatigue Load

open access: yesEnergies, 2022
With the participation of wind power in grid frequency modulation, the fatigue load of the wind turbine increases accordingly. A new control method that considers both fatigue load and output power of wind turbine (WT) is proposed in this paper. A linear

Total roto-translational variation [PDF]

open access: yesNumerische 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 ...

Continuous-Domain Formulation of Inverse Problems for Composite Sparse-Plus-Smooth Signals

open access: yesIEEE Open Journal of Signal Processing, 2021
We present a novel framework for the reconstruction of 1D composite signals assumed to be a mixture of two additive components, one sparse and the other smooth, given a finite number of linear measurements.

Remote sensing images destriping using unidirectional hybrid total variation and nonconvex low-rank regularization

open access: yesJournal of Computational and Applied Mathematics, 2020
In this paper, we propose a novel model for remote sensing images destriping, which includes the Schatten 1 ∕ 2 -norm and the unidirectional first-order and high-order total variation regularization.
