Improving non-local video denoising with local binary patterns and image quantization
(Sociedade Brasileira de Computação - SBCUniversidade Federal de São Paulo - UNIFESPInstituto Nacional de Pesquisas Espaciais - INPESão José dos Campos, 2016-10)
The most challenging aspect of video and image denoising is to preserve texture and small details, while filtering out noise. To tackle such problem, we present two novel variants of the 3D Non-Local Means (NLM3D) which ...
DENOISING BASED ON NON LOCAL MEANS FOR ULTRASOUND IMAGES WITH SIMULTANEOUS MULTIPLE NOISE DISTRIBUTIONS
(Ieee, 2014-01-01)
In this paper, an extension of the framework proposed by Deledalle et al.[1] for Non Local Means (NLM) method is proposed. This extension is a general adaptive method to denoise images containing multiple noises. It takes ...

First passage time on pattern formation in a non-local Fisher population dynamics
(De Gruyter, 2013-12)
We use stochastic dynamics to develop the patterned attractor of a non?local extended system. This is done analytically using the stochastic path perturbation approach scheme, where a theory of perturbation in the small ...
