Hyperspectral images due to their higher spectral resolution are increasingly being used for various remote sensing applications including information extraction at subpixel level. Typically whenever an object gets spectrally resolved but not spatially, m... see more

Nas áreas de Visão de Máquina e Fotogrametria as feições lineares extraídasde uma imagem podem ser utilizadas tanto como primitivas de umarepresentação vetorial em meio digital, quanto como controle para permitir adeterminação de elementos de orientação i... see more

Short-term high-resolution quantitative precipitation forecasting (QPF) is very important for flash-flood warning, navigation safety, and other hydrological applications. This paper proposes a subpixel-based QPF algorithm using a pyramid Lucas–Kanade opti... see more

High-resolution water mapping with remotely sensed data is essential to monitoring of rainstorm waterlogging and flood disasters. In this study, a modified linear spectral mixture analysis (LSMA) method is proposed to extract high-precision water fraction... see more

In July 2001 an aerial survey with MIVIS (Multispectral Infrared and Visible Spectrometer) hyperspectral sensor andan in situ survey campaign were performed on Venice lagoon to map benthic macro-algae and sea phanerogams distribution.On MIVIS VIS spectral... see more

Las metodologías unitemporales habitualmente utilizadas para cartografiar el área afectada por un incendio forestal se basan en la clasificación de una imagen NDVI post-incendio; sin embargo, presentan algunas limitaciones. Este trabajo propone una metodo... see more

This paper presents an experimental assessment of photogrammetric targets and subpixel location techniques to be used with low contrast images such as images acquired by hyperspectral frame cameras. Eight different target patterns of varying shape, backgr... see more
