The use of phase information present in complex multi polarized images may increase the classification results. Thus, the coherence is one attribute that may be extracted from these images and used to distinguish some land cover classes. Therefore, its discriminatory capability for land use and land cover classification is analyzed. The analysis is based on the classification results of a region classifier,...
The objective of this article is to evaluate the influence of the cross-talk and channel imbalance calibration on the estimation of the entropy and the alpha images. Few studies can be found in SAR literature concerning the influence of the polarimetric image calibration process on the target decomposition methods and their consequences on the characterization and discrimination of different ground...
The main objective of this work is to evaluate the potential of L band PolSAR data to discriminate deforestation increment. In order to achieve this purpose, it was performed a coherent attributes exploratory analysis and a Maximum Likelihood - ICM (Iterated Conditional Modes) classification of R99B sensor L band PolSAR data. The PolSAR data classification obtained good agreement with PRODES Digital...
Schistosomiasis mansoni is a disease with social and behavioral characteristics, and distributed mainly in poor regions of Brazil. From 1995 to 2005 more than a million positive cases of the disease were reported, 27% of them reported in Minas Gerais state. The objective of this work is to estimate the prevalence risk of schistosomiasis in the Minas Gerais state through the characterization of the...
