Description

I can't seem to get distanceTransform to do anything to my input images using the Python bindings

The the problem can be reproduced with the following code:

import numpy as np
import cv2

im = np.zeros( (10, 10), dtype = np.uint8)
im[5,5] = 255

imDT = cv2.distanceTransform(im, cv.cv.CV_DIST_L1, cv.cv.CV_DIST_MASK_5)

I've tried different combinations of type and mask parameters, but the output is always the same as the input.

Please delete. Realized the function treats zeros as edges.
