1. DESHADOWING OF HIGH SPATIAL RESOLUTION IMAGERY APPLIED TO URBAN AREA DETECTION
Abstract Different built-up structures usually lead to large regions covered by shadows, causing partial or total loss of information present in urban environments. In order to mitigate the presence of shadows while improving the urban target discrimination in multispectral images, this paper proposes an automated methodology for both detection and recovery

2. Space-Temporal analysis of suspended sediment in low concentration reservoir by remote sensing
RESUMO O estudo de pequenos reservatórios e com baixa concentração de sedimentos em suspensão (CSS) ainda é um desafio para o sensoriamento remoto. Neste trabalho estimamos a CSS a partir das propriedades óticas da água e de imagens orbitais. Realizamos campanhas em datas escolhidas em função do calendário de passagem dos sensores, sazonalidade das

4. Assigning dates and identifying areas affected by fires in Portugal based on MODIS data
ABSTRACT An automated procedure is here presented that allows identifying and dating burned areas in Portugal using values of daily reflectance from near-infrared and middle-infrared bands, as obtained from the MODIS instrument. The algorithm detects persistent changes in monthly composites of the so-called (V,W) Burn-Sensitive Index and the day of maximum c

5. Interaction between affordance and handedness recognition: a chronometric study
The visualization of tools and manipulable objects activates motor-related areas in the cortex, facilitating possible actions toward them. This pattern of activity may underlie the phenomenon of object affordance. Some cortical motor neurons are also covertly activated during the recognition of body parts such as hands. One hypothesis is that different subpo

6. New head-mounted display system applied to endoscopic management of upper urinary tract carcinomas
Purpose We tested a new head-mounted display (HMD) system for surgery on the upper urinary tract. Surgical Technique Four women and one man with abnormal findings in the renal pelvis on computed tomography and magnetic resonance imaging underwent surgery using this new system. A high definition HMD (Sony, Tokyo, Japan) is connected to a flexible uretero

7. Horizontal positional accuracy of Google Earth's imagery over rural areas: a study case in Tamaulipas, Mexico
Due to the popularity of Google Earth (GE), users commonly assume that it is a credible and accurate source of information. Consequently, GE's imagery is frequently used in scientific and others projects. However, Google states that data available in their geographic products are only approximations and, therefore, their accuracy is not officially documented
