Class ContourTracer

java.lang.Object
boofcv.alg.filter.binary.ContourTracer

public class ContourTracer
extends Object
Used to trace the external and internal contours around objects for LinearContourLabelChang2004. As it is tracing an object it will modify the binary image by labeling. The input binary image is assumed to have a 1-pixel border that needs to be compensated for.
