Seeded Watershed 3d

image =	seededWatershed3dImg (inIntImg3d,inLabMarkImg3d,inWatershedOutputMode)
image =	seededWatershed3dImg (inIntImg3d,inLabMarkImg3d,inWatershedOutputMode,inOptWatershedProcMode)

Detailed Description

seeded watershed 3d algorithm

Watershed algorithm allows to partition an input grey image InIntImg3d, associated to a marker image InLabMarkImg3d, into area of influence. This is a classical technic used for segmentation purposes.

A detailed description of this algorithm is provided in 2d case, see Seeded Watershed 2d.

Note

this algorithm has been packaged for easy separation in classical cases, see :

• Watershed Binary Separation 3d for binary image separation
• Watershed Grey Separation 3d for grey image separation

Warning

This algorithm will not be distributed, flooding processing computation and memory are proceeded on local computer.
