Revision history [back]

I am following the OpenCV tutorial about image contours and creating the outline of a shape, however on the final line of the code that has been provided I receive the error:

TypeError: image is not a numpy array, neither a scalar

My code reads:

import numpy as np import cv2

im = cv2.imread("shapes_and_colors.png") imgray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY) ret,thresh = cv2.threshold(imgray,127,255,0) im2, contours, hierarchy = cv2.findContours(thresh,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE) cv2.drawContours("shapes_and_colors.png", contours, -1, (0,255,0), 3)

Any help would be greatly appreciated :)

Thanks!
