Long Description
This application computes a global mean and standard deviation for each band of a set of images and optionally saves the results in an XML file. The output XML is intended to be used as an input for the TrainImagesClassifier application to normalize samples before learning. You can also normalize the image with the XML file in the ImageClassifier application.
Parameters
Input images (il): List of input image filenames.
Background Value (bv): Background value to ignore in computation of statistics.
Output XML file (out): XML filename where the statistics are saved for future reuse.
Available RAM (Mb) (ram): Available memory for processing (in MB)
Load otb application from xml file (inxml): Load otb application from xml file
Save otb application to xml file (outxml): Save otb application to xml file
Limitations
Each image of the set must contain the same bands as the others (i.e. same types, in the same order).
