Class BinaryContourHelper

java.lang.Object

boofcv.abst.filter.binary.BinaryContourHelper

public class BinaryContourHelper
extends Object

Helper function that makes it easier to adjust the size of the binary image when working with a padded or unpadded contour finding algorithm. Creating a copy of the input image can be avoided when finding contours if the binary image is expanded to have a contour in advance. Slight speed improvement and lower memory usage.
