Investigations on the full polarimetric PALSAR data to discriminate macrophytes species in the Amazon floodplain wetland
(2010-12-01)
The purpose of this work is to evaluate the capacity of full polarimetric L band data to discriminate macrophyte species in Amazon wetland. Fieldwork was carried out almost simultaneously to the acquisition of the full ...

AUTOMATICALLY DETECTING TEXTUAL CONTENT IN HIGH-RESOLUTION IMAGES
(2021-01-01)
Classifying targets in satellite images is a nontrivial task which requires dealing with a large number of undesirable elements such as clouds, building shadows and other unexpected objects. Among these, a commonly found ...
Spatiotemporal forecast with local temporal drift applied to weather patterns in Patagonia
(Springer, 2020-06-01)
Geostatistics was developed to generate maps or 3D models interpolating observed values in space. The so-called spatiotemporal geostatistic applies the same principles to estimate observed values that have both spatial and ...
Learning how to extract rotation-invariant and scale-invariant features from texture images
(Scopus, 2008)
Learning how to extract texture features from noncontrolled environments characterized by distorted images is a still-open task. By using a new rotation-invariant and scale-invariant image descriptor based on steerable ...
Morphological Analysis of Pressure Injury Images
(IEEE, 2018)
This paper details the morphological analysis of pressure injuries when using a novel methodology developed to process medical images, intended to de-compose the contained information in different contrast levels. This ...
MARDI: Marca d'água Digital Robusta via Decomposição de Imagens : uma proposta para aumentar a robustez de técnicas de marca d'água digital
(Universidade Estadual Paulista (Unesp), 2018-07-27)
Com a crescente evolução dos equipamentos eletrônicos, muitos dados digitais têm sido produzidos, copiados e distribuídos com facilidade, gerando uma grande preocupação com a sua segurança. Dentre as várias técnicas usadas ...
Single image non-uniform blur kernel estimation via adaptive basis decomposition.
(arXiv, 2021)
Characterizing and removing motion blur caused by camera shake or object motion remains an important task for image restoration. In recent years, removal of motion blur in photographs has seen impressive progress in the ...
Stabilization of new carbon inputs rather than old carbon decomposition determines soil organic carbon shifts following woody or herbaceous vegetation transitions
(Springer, 2016-12)
Background and aims: Although numerous studies have quantified the effects of land-use changes on soil organic carbon (SOC) stocks, few have examined simultaneously the weight of carbon (C) inputs vs. outputs in shaping ...
