Uses a flooding algorithm to set all voxels that are not a regional extrema to the max or min of the pixel type.
This is the class used by ValuedRegionalMinimaImageFilter and ValuedRegionalMaximaImageFilter. There is no suppression of regional minima based on dynamics, as available in HMinimaImageFilter. This flooding algorithm is a very simple one, but I'm not sure where it came from - I certainly didn't invent it.
Let's consider the case of regional minima. The basic algorithm is: Boundary conditions are such that the image is logically surrounded by a border that is either maximal or minimal for the pixel type. An optimized version could explicitly set the border to avoid the need for boundary checks. For regional minima the boundary is set to the maximal value for the pixel type.
Pixels are visited in raster order. The neighbors of each pixel are examined. If any neighbor is greater than the centre, then the centre pixel cannot be a regional minima. The centre pixel is part of a flat region (consisting of at least one pixel) that is therefore not a regional minima either. This region is set to the maximum value for the pixel type using a flooding algorithm.
There are some minor complications that prevent pixels being examined more than once – basically check that the output value is less than the maximum for the pixel type.
The implementation uses the functor model from itkMaximumImageFilter.
