Raster segmentation.
Raster segmentation following the choosed segmentation strategy.
- Note
- The created label image will be written to the raster instance pointed by m_outRasterPtr (in this case the output band must also be passed by m_outRasterBand ); or written to a new raster instance created inside the given data source pointed by m_outDataSourcePtr (in this case the data set name must be supplied - m_outDataSetName ).
