Method Detail

equivalentEllipses

public static final Ellipse[] equivalentEllipses(ij.process.ImageProcessor image,
                                                 int[] labels,
                                                 ij.measure.Calibration calib)

Computes equivalent ellipse of each region in input label image.

Parameters:

image - the input image containing region labels

labels - the array of labels within the image

calib - the calibration of the image

Returns:

an array of Ellipse representing the calibrated coordinates of the equivalent ellipse of each region

createTable

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

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

Parameters:

map - the mapping between labels and Inertia Ellipses

Returns:

a ResultsTable that can be displayed with ImageJ.

analyzeRegions

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

Computes the equivalent ellipse of each region within the input label image.

Specified by:

analyzeRegions in class RegionAnalyzer2D<Ellipse>

Parameters:

image - the input image containing region labels

labels - the array of labels within the image

calib - the calibration of the image

Returns:

an array of Ellipse representing the calibrated coordinates of the inertia ellipse of each region
