“…The magnitude of the change vector (Euclidean distance of CVA or CVAED) and the spectral information divergence (SID) similarity measures are applied to detect the changed area [24,41]. Subspace-based change-detection (SCD) algorithms, that is, original SCD, adaptive SCD (ASCD), and local SCD (LSCD), are also employed [26].…”

“…In this study, two representative normalized spectral measures are used. First, the spectral angle distance (SAD) measure is used to calculate the spectral similarity between the spectra of two pixels in the original multitemporal hyperspectral images [41]. We assume that = ( 1 , 2 , .…”

“…Os endmembers foram selecionados a partir da inspeção de espectros extremos de pixels extraídos pelo PPI e projetados como pontos num visualizador n-dimensional contendo os eixos das imagens MNFs de maior ordem. A rotação interativa dos eixos das imagens MNFs e a observação dos pixels mais puros no espaço n-dimensional, permitiu a seleção de endmembers para serem utilizados nas etapas de classificação hiperespectral propriamente dita, através dos algoritmos Spectral Angle Mapper (SAM) (Kruse et al 1993) e Mixture Tuned Matched Filtering (MTMF) (Boardman et al 1995, Boardman 1998.…”

“…Dois métodos de classificação supervisionada, o Spectral Angle Mapper (SAM) (Kruse et al 1993) e o Mixture Tuned Matched Filtering (MTMF) (Boardman et al 1995), originalmente concebidos para classificação espectral de imagens hiperespectrais de sensoriamento remoto, foram aplicados e testados com dados aerogeofísicos. O objetivo foi mapear as assinaturas magnéticas e gamaespectrométricas dos litotipos e estruturas aos quais se associam as ocorrências e as minas de ouro da área de estudo.…”
