Method Details

maxFeretDiameters

public static final PointPair3D[] maxFeretDiameters(ij.ImageStack image,
int[] labels,
ij.measure.Calibration calib)

Computes Feret diameters as a PointPair3D for each of the specified regions within a label map.

Parameters:

image - the 3D label map corresponding to the label image

labels - the array of region labels to process

calib - the spatial calibration of the image

Returns:

the array of 3D Feret diameter results

maxFeretDiameter

public static final PointPair3D maxFeretDiameter(java.util.ArrayList<? extends Point3D> points)

Computes Maximum Feret diameter of a set of points. Note: it is often a good idea to compute convex hull before computing Feret diameter.

Parameters:

points - a collection of planar points

Returns:

the maximum Feret diameter of the point set

createTable

public ij.measure.ResultsTable createTable(java.util.Map<java.lang.Integer,PointPair3D> maxDiamsMap)

Converts the result of maximum Feret diameters computation to a ResultsTable that can be displayed within ImageJ.

Parameters:

maxDiamsMap - the map of PointPair3D for each label within a label image

Returns:

a ResultsTable instance

analyzeRegions

public PointPair3D[] analyzeRegions(ij.ImageStack image,
int[] labels,
ij.measure.Calibration calib)

Computes maximum Feret Diameter for each label of the input label image. Computes diameter between corners of image pixels, so the result is always greater than or equal to one.

Specified by:

analyzeRegions in class RegionAnalyzer3D<PointPair3D>

Parameters:

image - a label image (8, 16 or 32 bits)

labels - the set of labels within the image

calib - the spatial calibration of the image

Returns:

an array of PointPair3D representing the coordinates of extreme points, in calibrated coordinates.
