1. Processamento e modelagem de dados geofísicos e imagens ASTER aplicados à interpretação geológica e prospecção mineral na Província Aurífera de Alta Floresta, MT / Processing and modeling of geophysical data and ASTER images applied to geological interpretation and mineral exploration in the Alta Floresta Gold Province, MT
The Alta Floresta Gold Province (AFGP) is located in the central-southern Amazon craton between the limits of the Ventuari-Tapajos (1.95-1.8 Ga) and Rio Negro-Juruena (1.8-1.55 Ga) provinces. In its eastern segment there are more than one hundred gold deposits hosted in volcanic and plutonic rocks and concentrated along the Peru-Trairao Belt in a NW-SE direc

2. Modeling and rendering of real environments
The use of detailed geometric models is a critical factor for achieving realism in most computer graphics applications. In the past few years, we have observed an increasing demand for faithful representations of real scenes, primarily driven by applications whose goal is to create extremely realistic experiences by building virtual replicas of real environm

3. A SPINE 3D MODELING SYSTEM BASED ON X-RAY IMAGES / UM SISTEMA DE MODELAGEM 3D DE COLUNA VERTEBRAL BASEADO EM IMAGENS DE RAIOS-X
Research involving computer graphics and laboratory exams has contributed much to the quality of the Medical diagnose. One aspect of these researches is directly related to 3D reconstruction of anatomical structures of the human body, especially the spine. The sedentary lifestyle and the high dependence of computers have increased the postural problems of th

5. RECONSTRUCTION OF SCENES FROM IMAGES BY COARSE-TO-FINE SPACE CARVING / RECONSTRUÇÃO DE CENAS A PARTIR DE IMAGENS ATRAVÉS DE ESCULTURA DO ESPAÇO POR REFINAMENTO ADAPTATIVO
The reconstruction of scenes from imagens has received special attention from researchers of the areas of computer vision, computer graphics and geometric modeling. As examples of application we can mention image-based scene reconstruction, modeling of complex as-built objects, construction of virtual environments and telepresence. Among the most successful

6. Restauração de imagens do satélite Landsat-7. / Restoration of LANDSAT-7 satellite images.
The techniques of image restoration are oriented for the modeling of the degradation and recovery of the original signal that was degraded during the process of image formation. In Remote Sensing, sensor?s nominal spatial resolution, that defines the precision with which details of objects of interest in the image are perceivable, is one of the most importa

7. Malignant lesion segmentation in contrast-enhanced breast MR images based on the marker-controlled watershed
Breast tumor volume measured on MRI has been used to assess response to neoadjuvant chemotherapy. However, accurate and reproducible delineation of breast lesions can be challenging, since the lesions may have complicated topological structures and heterogeneous intensity distributions. In this article, the authors present an advanced computerized method to

8. Development of a novel microperfusion chamber for determination of cell membrane transport properties.
A novel microperfusion chamber was developed to measure kinetic cell volume changes under various extracellular conditions and to quantitatively determine cell membrane transport properties. This device eliminates modeling ambiguities and limitations inherent in the use of the microdiffusion chamber and the micropipette perfusion technique, both of which hav
