Method Detail

largestInscribedCircles

public static final Circle2D[] largestInscribedCircles(ij.process.ImageProcessor labelImage,
                                                       int[] labels,
                                                       ij.measure.Calibration calib)

Computes largest inscribed disk of each region within a label image. Regions must be disjoint.

Parameters:

labelImage - the input image containing region labels

labels - the set of labels within the image

calib - the spatial calibration of the image

Returns:

an array of Circle2D representing the inscribed circles of each region, in calibrated coordinates

createTable

public ij.measure.ResultsTable createTable(Map<Integer,Circle2D> map)

Utility method that transforms the mapping between labels and inscribed circle instances into a ResultsTable that can be displayed with ImageJ.

Parameters:

map - the mapping between labels and Circle2D instances

Returns:

a ResultsTable that can be displayed with ImageJ.

analyzeRegions

public Circle2D[] analyzeRegions(ij.process.ImageProcessor labelImage,
                                 int[] labels,
                                 ij.measure.Calibration calib)

Computes largest inscribed disk of each region within a label image. Regions must be disjoint.

Specified by:

analyzeRegions in class RegionAnalyzer2D<Circle2D>

Parameters:

labelImage - the input image containing region labels

labels - the set of labels within the image

calib - the spatial calibration of the image

Returns:

an array of Circle2D representing the inscribed circles of each region, in calibrated coordinates
