public static List<org.anchoranalysis.spatial.point.Contour> contoursForObject(org.anchoranalysis.image.voxel.object.ObjectMask object) throws org.anchoranalysis.core.exception.OperationFailedException

Calculates the extreme outer contours from an ObjectMask as OpenCV defines contours.

The setting Imgproc.RETR_EXTERNAL defines the extreme outer contours. Please see the related OpenCV documentation.

No approximation occurs of the contours' points.

Parameters:

object - the object whose contours should be found.

Returns:

a newly created list, containing the extreme outer contours.

Throws:

org.anchoranalysis.core.exception.OperationFailedException - if the countour cannot be calculated.
