The use of discrete Markov random fields in reservoir characterization
(Elsevier Science BvAmsterdamHolanda, 2001)
Bayesian reconstruction for digital breast tomosynthesis using a non-local Gaussian Markov random field a priori model
(2019-01-01)
Noise is an intrinsic property of every imaging system. For imaging systems using ionizing radiation, such as digital breast tomosynthesis (DBT) or digital mammography (DM), we strive to ensure that x-ray quantum noise is ...
Mixed-state Markov models in image motion analysis
(Springer Verlag Berlín, 2011)
When analyzing motion observations extracted from image sequences one notes that the histogram of the velocity magnitude at each pixel shows a large probability mass at zero velocity, while the rest of the motion values ...
Avanços recentes em caracterização e classificação de imagens de texturas: explorando teoria da informação, aprendizado profundo e de variedades
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2020-04-30)
The task of extracting features from images is a very important activity for many computer vision and image processing applications. Especially the characterization and identification of textures is a fundamental issue in ...
Nonlocal Markovian models for image denoising
(Is&t & Spie, 2016-01-01)
Currently, the state-of-the art methods for image denoising are patch-based approaches. Redundant information present in nonlocal regions (patches) of the image is considered for better image modeling, resulting in an ...
A novel MAP-MRF approach for multispectral image contextual classification using combination of suboptimal iterative algorithms
(ELSEVIER SCIENCE BV, 2010)
In this paper we present a novel approach for multispectral image contextual classification by combining iterative combinatorial optimization algorithms. The pixel-wise decision rule is defined using a Bayesian approach ...
Genomic characterization of salmonella Cerro ST367, an emerging Salmonella subtype in cattle in the United States
(BioMed Central Ltd., 2014-06)
Background: Within the last decade, Salmonella enterica subsp. enterica serovar Cerro (S. Cerro) has become one of
the most common serovars isolated from cattle and dairy farm environments in the northeastern US. The fact ...
