 The application asks for images statisctics as input (XML file generated with the ComputeImagesStatistics application) and a SVM model (text file) generated with the ImagesSVMClassifier application.
 It will compute the global confusion matrix and kappa index and also the precision, recall and F-score of each class.</p><p style=" margin-top:14px; margin-bottom:12px; margin-left:0px; margin-right:0px;
