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 an input for the TrainImagesSVMClassifier application to normalize samples before learning.

Parameters

• [param] Input images (-il): List of input images filenames.

• [param] Output XML file (-out): XML filename where the statistics are saved for future reuse

Limitations

The set of input images must have the same number of bands. Input images must be of the same number, type and order of bands.
