Remarks

The OIV.ImageViz.Engines.MathematicalMorphology.GeodesicTransformations.SoRegionalExtremaProcessing engine computes the regional or relative fast maxima and minima in a grayscale image, , and displays the result in a binary image, . This algorithm is based on [1] and uses a recursive method combined with a geodesic propagation. To avoid getting too many regions in the output image, input should first be smoothed with a low-pass filter or with the dual numerical reconstruction algorithm.

Case Minima

This case of use computes the regional or relative minima in a grayscale image and creates a binary image containing these minima.

A regional minimum is a set of connected pixels such that:

  • Pixels belonging to have the same intensity .

  • Pixels connected to , but not belonging to (neighbors), have an intensity greater than .

Case Maxima

This engine computes the regional or relative maxima in a grayscale image and creates a binary image containing these maxima.

A regional maximum is a set of connected pixels such that:

  • Pixels belonging to have the same intensity .

  • Pixels connected to , but not belonging to (neighbors), have an intensity greater than .
