OpenCV Contours - need more than 2 values to unpack

Question

I am trying to implement contours using the following code..

im = cv2.imread(\'C:\\Users\\Prashant\\Desktop\\T.jpg\')
imgray = cv2.cvtColor(im,cv2.COLOR_BGR2         


        

Answer 1

• findContours returns only two values. so use just,

So use

contours, hierarchy=cv2.findContours(thresh,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE)
