public class SoHExtremaWatershedProcessing
extends SoImageVizEngine

SoHExtremaWatershedProcessing engine computes the watershed lines of a grayscale image. This engine computes the watershed lines of a grayscale image. It directly uses the image for black objects and the inverted image for white objects. You can adjust the contrast level which is used to reduce the number of markers for the watershed process.

This engine is a high-level combination of watershed, distance transform and numerical reconstruction algorithms. There is a limitation to the separating ability: if some particles overlap too much, they will not be separated. This engine can be used on the gradient modulus to compute best-fit contours.

Notice: This engine requires to preliminarily load the whole input data set into memory to be computed. As a consequence the input data set will be automatically loaded before the execution of this engine, ignoring the maximum memory parameter of the SbImageDataAdapterHelper.getAppropriateAdapter function or SoFileDataAdapter class If the input data set cannot fit in memory, this engine will fail during its computation.
