Package com.openinventor.imageviz.engines.imagesegmentation.regiongrowing Description

This group contains segmentation engines based on the propagation of a seed. Watershed

The principle of the watershed algorithm is called immersion, and it is based on a simulation of the rise of water from a set of markers. The level p is flooded at a uniform speed from the fronts coming from level p-1 and the local minima appear at level p. A point of the watershed appears when two distinct fronts join.

Figure 1: The watershed principleFigure 2: Example of how the result depends on the choice of markers Our watershed implementation is based on:

  • L. Vincent and P. Soille. Watersheds in Digital Spaces: An Efficient Algorithm Based on Immersion Simulations. IEEE Transactions on Pattern Analysis and Machine Intelligence archive, Volume 13, Issue 6. June 1991.
