Video denoising via empirical bayesian estimation of space-time patches

P Arias, JM Morel - Journal of Mathematical Imaging and Vision, 2018 - Springer
In this paper we present a new patch-based empirical Bayesian video denoising algorithm.
The method builds a Bayesian model for each group of similar space-time patches. These …

The sample complexity of dictionary learning

D Vainsencher, S Mannor… - Proceedings of the 24th …, 2011 - proceedings.mlr.press
A large set of signals can sometimes be described sparsely using a dictionary, that is, every
element can be represented as a linear combination of few elements from the dictionary …

Entropy based dictionary learning for image classification

A Abdi, M Rahmati, MM Ebadzadeh - Pattern Recognition, 2021 - Elsevier
In this paper, a new discriminative dictionary learning algorithm is introduced. An entropy
based criterion is embedded into the objective function to enforce a proper structure for the …

Unified single-image and video super-resolution via denoising algorithms

A Brifman, Y Romano, M Elad - IEEE Transactions on Image …, 2019 - ieeexplore.ieee.org
Single image super-resolution (SISR) aims to recover a high-resolution image from a given
low-resolution version of it. Video super-resolution (VSR) targets a series of given images …

Image and video denoising using adaptive dual-tree discrete wavelet packets

J Yang, Y Wang, W Xu, Q Dai - IEEE transactions on circuits …, 2009 - ieeexplore.ieee.org
We investigate image and video denoising using adaptive dual-tree discrete wavelet
packets (ADDWP), which is extended from the dual-tree discrete wavelet transform (DDWT) …

Robust Kronecker product video denoising based on fractional-order total variation model

G Chen, J Zhang, D Li, H Chen - Signal Processing, 2016 - Elsevier
Most existing sparse representation-based video denoising algorithms assume video noise
is additive Gaussian white noise, which is often violated in practice. In this paper, a robust …

Towards a bayesian video denoising method

P Arias, JM Morel - Advanced Concepts for Intelligent Vision Systems: 16th …, 2015 - Springer
The quality provided by image and video sensors increases steadily, and for a fixed spatial
resolution the sensor noise has been gradually reduced over the years. However, modern …

Nonlocal video denoising, simplification and inpainting using discrete regularization on graphs

M Ghoniem, Y Chahir, A Elmoataz - Signal Processing, 2010 - Elsevier
We present nonlocal algorithms for video denoising, simplification and inpainting based on
a generic framework of discrete regularization on graphs. We express video denoising …

Measuring noise correlation for improved video denoising

A Kokaram, D Kelly, H Denman… - 2012 19th IEEE …, 2012 - ieeexplore.ieee.org
The vast majority of previous work in noise reduction for visual media has assumed
uncorrelated, white, noise sources. In practice this is almost always violated by real media …

Dictionary learning enhancement framework: Learning a non-linear mapping model to enhance discriminative dictionary learning methods

A Abdi, M Rahmati, MM Ebadzadeh - Neurocomputing, 2019 - Elsevier
In this paper, a new framework is presented to enhance the reconstruction and
discrimination capabilities of existing discriminative dictionary learning methods. In the …
