Method Detail

regionsCorners

public static final Map<Integer,ArrayList<Point3D>> regionsCorners(ij.ImageStack image,
                                                                   int[] labels)

Returns a set of points located at the corners of a binary particle. Point coordinates are integer (ImageJ locates pixels in a [0 1]^d area.

Parameters:

image - a binary image representing the particle

labels - the list of labels to process

Returns:

a list of points that can be used for convex hull computation

regionsCornersArray

public static final ArrayList<Point3D>[] regionsCornersArray(ij.ImageStack image,
                                                             int[] labels)

Returns a set of points located at the corners of a binary particle. Point coordinates are integer (ImageJ locates pixels in a [0 1]^d area.

Parameters:

image - a binary image representing the particle

labels - the list of labels to process

Returns:

for each label, an array of points
