Web.NET Framework wrapper for OpenCV 2.4.10. Contribute to shimat/opencvsharp_2410 development by creating an account on GitHub. WebThe watershed is a classical algorithm used for segmentation, that is, for separating different objects in an image. Starting from user-defined markers, the watershed algorithm treats pixels values as a local topography (elevation). The algorithm floods basins from the markers until basins attributed to different markers meet on watershed lines.
