![]() ![]() (a) searching for the best subset of features using any of five statistical distance ![]() Determine the best spectral features to use for a given classification using.A covariance estimation scheme (LOOC)Ĭan optimize that estimate for small training sets. Statistics" also allows one to improve the extent to which the defined class statisticsįit the composite of all data in the data set. ![]() Use in evaluating classification results quantitatively. Define classes via designating rectangular or polygonal training fields or mask image files, compute field and class statistics, and define test fields for.Use of clustering followed by ECHO spectral/spatial classification provides an effective multivariate scene segmentation scheme. Cluster statistics can also be saved as class statistics. Save the results for display as a thematic map. ![]()
