Default constructor.

Method Detail

orientedBoundingBox

public static final OrientedBox2D orientedBoundingBox(ArrayList<? extends Point2D> points)

Computes the object-oriented bounding box of a set of points.

Parameters:

points - a list of points (not necessarily ordered)

Returns:

the oriented box of this set of points.

orientedBoundingBox

public static final OrientedBox2D orientedBoundingBox(ArrayList<? extends Point2D> points,
                                                      ij.measure.Calibration calib)

Computes the object-oriented bounding box of a set of points, computing convex hull in pixel coordinates. Due to numerical computation, this versions is usually more stable than computing the convex hull on the calibrated points.

Parameters:

points - a list of points, in pixel coordinates

calib - the spatial calibration of the points

Returns:

the oriented box of this set of points, in calibrated coordinates

createTable

public ij.measure.ResultsTable createTable(Map<Integer,OrientedBox2D> results)

Description copied from interface: RegionAnalyzer

Utility method that converts the detailed results of the RegionAnalyzer.analyzeRegions(ImagePlus) method into an instance of ResultsTable to facilitate display by ImageJ.

Parameters:

results - the mapping between each region label and the result of the analysis

Returns:

an instance of ResultsTable containing results presented in a tabular format.

analyzeRegions

public OrientedBox2D[] analyzeRegions(ij.process.ImageProcessor image,
                                      int[] labels,
                                      ij.measure.Calibration calib)

Description copied from class: RegionAnalyzer2D

Computes an instance of the generic type T for each region in input label image.

Specified by:

analyzeRegions in class RegionAnalyzer2D<OrientedBox2D>

Parameters:

image - the input image containing label of particles

labels - the array of labels within the image

calib - the spatial calibration of the image

Returns:

an array of the type used to represent the analysis result of each region
