摘要: The aim of this work is the comparative study methods for calculating spectral anomalies from imaging spectrometry test in several areas Central Volcanic Range (CVC) Costa Rica. In detection anomalous responses assumed no prior knowledge targets, so that pixels are automatically separated according to their information significantly differentiated with respect a background be estimated, either globally entire scene, locally by image segmentation.We used ranges visible-near infrared (VNIR), shortwave (SWIR) and thermal (TIR) data cubes hiperepectrales HyMAP airborne sensors MASTER. We have designed experiments on natural scenes CVC, urban semi-urban different complexity, analyzing behavior standard RX anomaly detector approaches based dimensionality reduction. discuss results an approximation involvement as terrestrial counterparts planetary exploration.Revista Ciencias Espaciales, Volumen 8, Numero 2 Otono, 2015; 272-286
