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

As per the Current Opencv Versions cv2.findContours returns 2 Values and that is Contours and heirachy. Contours can be explained simply as a curve joining all the continuous points (along the boundary), having same color or intensity. The contours are a useful tool for shape analysis and object detection and recognition.
