Redução de ruído speckle em imagens de ultrassom com filtragem não-local e distâncias estocásticas
(Universidade Federal de São Carlos, 2017-12-08)
Ultrasound imaging is one of the most used modalities in medicine since it is low cost and has no ionizing radiation. However, ultrasound images are corrupted by a signal-dependent noise, known as speckle, causing a granular ...
Um conjunto de abordagens para a geração da matriz de rastreabilidade de requisitos com suporte de técnicas de inteligência computacional

Modelo preditivo de situações como apoio à consciência situacional e ao processo decisório em sistemas de resposta à emergência
(Universidade Federal de São Carlos, 2017-08-28)
Situation Awareness (SAW) is a concept widely used in areas that require critical decision making, and refers to the ability of an individual or team to perceive, understand and anticipate the future state of a current ...
Filtragem não-local do ruído Speckle em imagens SAR com modelagem estatística dos coeficientes da Wavelet de Haar e distâncias estocásticas
(Universidade Federal de São Carlos, 2018-06-04)
Due to the coherent processing of synthetic aperture radar (SAR) systems, multiplicative
speckle noise arises providing a granular appearance in SAR images. This kind of noise
makes it difficult to analyse and interpret ...
Automatic computational scheme for segmentation, volumetric assessment and analysis of multiple sclerosis lesions in magnetic resonance images of the human brain
(Universidade Federal de São Carlos, 2019-09-27)
Multiple Sclerosis (MS) is an inflammatory demyelinating (that is, with myelin loss) disease of the Central Nervous System (CNS). It is considered an autoimmune disease in which the immune system wrongly recognizes the ...

Mineração de regras de associação espaço-temporais temáticas aplicada a imagens de explosões solares
(Universidade Federal de São Carlos, 2018-09-14)
Introduction. Space weather analysis is a complex task that involves spatiotemporal data from satellite images added to data from daily bulletins.
These data are characterized as time series of georeferenced images and ...
Algoritmos para a redução de ruído Poisson e estimativa de parâmetros utilizando distâncias estocásticas
(Universidade Federal de São Carlos, 2018-06-14)
Noise is present in all applications of digital imaging. Due to its stochastic nature, it is impossible to determine exact procedures to completely remove noise from the image. Thus, the target signal may be affected during ...
