Long Description

Compute statistics (mean and standard deviation) of the features in a set of OGR Layers, and write them in an XML file. This XML file can then be used by the training application.

Parameters

• Vector Data (inshp): Name of the input shapefile

• Output XML file (outstats): XML file containing mean and variance of each feature.

• Feature (feat): List of features to consider for statistics.

• 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

Experimental. For now only shapefiles are supported.
