Tool Name	Watershed Segmentation (ViGrA)
Tool ID	4
Library ID	imagery_vigra
Version	1.0
Author(s)	O.Conrad (c) 2009

Description

Note that the watershed algorithm usually results in an oversegmentation (i.e., too many regions), but its boundary localization is quite good.
Based on the code example "watershed.cxx" by Ullrich Koethe.
