Esse artigo procura demonstrar, por simulação, que na estimativa de perfis de volume da vegetação por interferometria com múltiplas linhas de base, o pico de...
Uso de Algoritmos Genéticos na Seleção de Atributos para Classificação (2009)
De Regiões, Joelma Carla Santos, João Ricardo, F. Oliveira, Luciano V. Dutra
Abstract. The technological advances about remote sensing allows a better identification of urban targets in the images. The aim of this work is to classify automatically the urban spaces applying...
MODELING SPATIAL TREE PATTERNS IN THE TAPAJÓS FOREST USING INTERFEROMETRIC HEIGHT (2008)
Till Neeff, Gregory S. Biging, Luciano V. Dutra, Corina C. Freitas
The spatial distribution of very large trees in primary Amazon forest is extracted from a digital model of interferometric forest height by an approach of local maximum filtering. The spatial point...
Prrimary Forrest and Land Cover Contextual Classification using JERS-1 data . . . (2007)
INTRODUCTION Key questions in Amazonian studies are: how do deforested areas evolve? Are these areas left to regenerate after deforestation? Another question is how to classify different types of...
SAR Interferogram Phase Filtering based on the von Mises Distribution (2007)
Reinhold Huber, Luciano V. Dutra
Abstract- We propose the use of the Von Mises distribution for circular data to model interferometric phase images. Based on the kappa parameter of the Von Mises distribution a locally adaptive phase...

We study feature selection and classification for a land-cover mapping task from airborne high resolution AeS-1 data in radar X- and P-Band. The studied feature selection methods are the...
Luciano V. Dutra, Pesquisas Espaciais, Reinhold Huber, Sergio M. Soares
Two methodologies for rain forest mapping in Amazonia using textural features derived from JERS-1 data are presented. The first one uses a set of pass-band filters, called Laws filters, combined by...

Feature Selection for ERS 1/2 InSAR Classification: High Dimensionality Case (1998)
Reinhold Huber, Luciano V. Dutra
A systematic way of selection and assessment of the performance of a large number of texture features extracted from spaceborne interferometric SAR data and classified with different types of...
Feature Selection for ERS-1/2 InSAR Classification: High Dimensionality Case (1998)
Reinhold Huber, Luciano V. Dutra
this paper. We formulate the problem of feature selection as finding a mapping from the initial, possibly very high--dimensional, feature space of dimension D to a m--dimensional subspace, where m D....
Texture Edge Detection by Propagation and Shrinking (1980)
Dutra, Luciano V., Mascarenhas, Nelson D. A.
The problem of detecting edges between differently textured regions is important in the process of segmentation of remotely sensed images. However, the concept of texture is difficult to be precisely...
