## Detailed Description

Options object for generateWatershedSeeds().

Usage:

#include <vigra/watersheds.hxx>
Namespace: vigra

            IImage seeds(boundary_indicator.size());

            // detect all minima in 'boundary_indicator' that are below gray level 22
            generateWatershedSeeds(srcImageRange(boundary_indicator),
                                   destImage(seeds),
                                   SeedOptions().minima().threshold(22.0));

## Constructor & Destructor Documentation

SeedOptions | ( |  | ) |

Construct default options object.

Defaults are: detect minima without thresholding (i.e. all minima).

## Member Function Documentation

SeedOptions& minima | ( |  | ) |

Generate seeds at minima.

Default: true

SeedOptions& extendedMinima | ( |  | ) |

Generate seeds at minima and minimal plateaus.

Default: false

SeedOptions& levelSets | ( |  | ) |

Generate seeds as level sets.

Note that you must also set a threshold to define which level set is to be used.
Default: false

SeedOptions& levelSets | ( | double | threshold | ) |

Generate seeds as level sets at given threshold.

Equivalent to `SeedOptions().levelSet().threshold(threshold)`
Default: false

SeedOptions& threshold | ( | double | threshold | ) |

Set threshold.

The threshold will be used by both the minima and level set variants of seed generation.
Default: no thresholding
