short itk::watershed::Boundary< TScalar, TDimension >::face_pixel_t::flow

Index of the direction of watershed flow through this pixel. A negative value indicates that the flow does not move out of the region. A positive value is the index into the pixel neighborhood of the facing chunk boundary into which flow moves.

Note that the range of values of the index depends on the the connectivity used by the watershed segmentation algorithm. If the WS algorithm uses city-block style connectivity (4-connectivity in 2D, 6-connectivity in 3D, etc) this could actually be a boolean value indicating inward or outward flow since there is only one valid neighbor to reference. For extensibility to other connectivities, this flow value can be used to index a number of different neighbors.
