public abstract class EvaluationMeasureContours
extends EvaluationMeasure

Class implements the super class for contour detection evaluation operators.

These operators need a segmentation image and a ground truth image. They evaluate a contour segmentation in comparison to the ground truth segmentation by an expert. Both images have to be region images and have to have the same size. The class is able to detect all regions (which a later identified by their pixel value) and their contours. In addition the class is able to allocate regions, that we know which region in the segmentation image belongs to which region in the ground truth image. This method just collects regions and region contours. If there are no regions in an image the accordingly lists (gtRegions, segRegions, gtContours, segContours) are not allocated.
