It would allow to use ogr fusion functionalities even with gdal version < 1.8.0
The implementation of the get_lenght method is based on the method available in OGRGeometryCollection class
The behaviour is not modify for otb compiled with gdal > 1.8.0.
The related compiles for now but there are remainig issues with layer deletation in the
related test

COMP:disable polygons stiching in LargeScaleSegmentation application for gdal version inf to 1.8.0 and return a warning

The code was first developed in the context of the CNES R&T study Venise by Julien Michel. The translation in a OTB application and some modifications were done by Jens Ziehn during his intership at CNES in 2011.
The aim of this application is to provide similar functionnality as the FeatureExtraction module in Monteverdi. For now it contains (hog, fourrier-mellin,histogram,haralick textures) and flusser moments.
There are some improvments to add to the application (documentation, compute features separately...)
