The output XML is intended to be used an input for the TrainImagesClassifier application to normalize samples before learning.<h2>Parameters</h2><ul><li><b>[param] -il</b> &lt;string&gt; List of input images filenames.. Mandatory: True. Default Value: &quot;0&quot;</li><li><b>[param] -bv</b> &lt;float&gt; Background value to ignore in statistics computation.. Mandatory: False. Default Value: &quot;0.0&quot;</li><li><b>[param] -out</b> &lt;string&gt; XML filename where the statistics are saved for future reuse.. Mandatory: False. Default Value: &quot;&quot;</li></ul><h2>Limitations</h2>Each image of the set must contain the same bands as the others (i.e. same types, in the same order).<h2>Authors</h2>OTB-Team<h2>See Also</h2>Documentation of the TrainImagesClassifier application.<h2>Example of use</h2><ul><li><p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">il: QB_1_ortho.tif</p></li><li><p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">out: EstimateImageStatisticsQB1.xml</p></li></ul></body></html>
