Detailed Description

Options object for generateWatershedSeeds().

Usage:

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

MultiArray<2, float>  boundary_indicator(w, h);
MultiArray<2, int>    seeds(boundary_indicator.shape());

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

Examples:

watershed.cxx.

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
