SoHExtremaProcessing engine. The SoHExtremaProcessing engine merges the regional minima or maxima.
This engine merges regional minima or maxima based on a contrast coefficient criterion h. It is useful for filtering noisy minima or maxima sets. It can also be used as particle markers in various algorithms, e.g. watershed detection.
Case Minima
The input is added to the contrast coefficient h, then a SoExtremaImpositionProcessing (case Erosion) is performed on the result of the addition.
The regional minima of the reconstructed image are called the H-Minima.
Case Maxima
The input is subtracted from the contrast coefficient h, then a SoExtremaImpositionProcessing (case Dilation) is performed on the result of the subtraction.
The regional maxima of the reconstructed image are called the H-Maxima.
