    Performance evaluation of different classifiers (Isoseg, Bhattacharyya, Maxver e Maxver-ICM), using CCD/CBERS-1 and ETM+/Landsat-7 fused images by Wilson Lins de Mello Filho, Camila Aguirre Góes, Melissa Carvalho

    Published 2007-06-01
    “…For this, pre-processing techniques (atmospheric, geometric and radiometric corrections), contrast enhancement (IHS data fusion and principal component analysis) and classification of CCD/CBERS-1 and ETM+/Landsat-7 images were done. Amongst all classifiers tested, Isoseg and Bhattacharyya presented best performance for the studied classes and the study area. …”

    Avaliação do desempenho de diferentes classificadores (Isoseg, Bhattacharyya, Maxver e Maxver-ICM), utilizando imagens CCD/CBERS-1 e ETM+/Landsat-7 fusionadas by Melissa Carvalho, Wilson Lins de Mello Filho, Camila Aguirre Góes

    Published 2006-12-01
    “…Para alcançar este objetivo foram utilizadas técnicas de pré-processamento (correções atmosférica, geométrica e radiométrica), realce (fusão IHS e análise por componentes principais) e classificação das imagens CCD/CBERS-1 e ETM+/Landsat-7. Dentre os classificadores testados, o Isoseg e o Bhattacharyya apresentaram melhor desempenho para a área de estudo e para as classes representadas. …”
