+//  This example shows the basic approch to perform object based analysis on a image.
+//  The input image is firstly segmented using the \doxygen{otb}{MeanShiftImageFilter}
+//  Then each segmented region is converted to a Map of labeled objects.
+//  After the \doxygen{otb}{RadiometricAttributesLabelMapFilter}  computes computes 
+//  radiometric attributes for each object.
+//  Images are supposed to be standard 4-bands image (B,G,R,NIR). The
+//  index of each channel can be set via the Set***ChannelIndex()
+//  accessors.
+//  
+//  This filter internally applies the
