Detailed Description

template<unsigned DIM, typename Pixel = float, typename PixelImage = float>
class segmentation::RegionModule< DIM, Pixel, PixelImage >

Virtual SegmentationModule specialization used to drive the LevelSet using some region evolution.

Author:

Mikael Rousson

Note:

This module has an image in member, and gives some functions to estimate histograms inside and outside a given LevelSet

You can fix the histogram of each region by setting their 'adaptative' attribute to false
