Detailed Description

template<class TImageType, class TSegmentationFilter>
class otb::StreamingImageToOGRLayerSegmentationFilter< TImageType, TSegmentationFilter >

This filter is a framework for large scale segmentation. It is a persistent filter that process the input image tile by tile. This filter is templated over the segmentation filter. This later is used to segment each tile of the input image. Each segmentation result (for each tile) is then vectorized using LabelImageToOGRDataSourceFilter (based on GDALPolygonize()). The output OGRDataSource of the LabelImageToOGRDataSourceFilter is a "memory" DataSource (ie all features of a tile are kept in memory). From here some optional processing can be done, depending on input parameters :

• Simplify option : If set to true, the SimplificationTolerance parameter is used to simplify all geometries, using the OGRGeometry::Simplify() method, based on Douglas-Peuker algorithm.
• FilterSmallObject option : if set to true, polygons with a size less than MinimumObjectSize (in pixels) are discarded. Finally all features contained in the "memory" DataSource are copied into the input Layer, in the layer specified with the SetLayerName() method.

Note

The Use8Connected parameter can be turn on and it will be used in GDALPolygonize(). But be carreful, it can create cross polygons !

The input mask can be used to exclude pixels from vectorization process. All pixels with a value of 0 in the input mask image will not be suitable for vectorization.
