Incorrect outcome of using Chain Approx None [closed]
Hi
When detecting a square object, i noted that when i used cv2.findContours which i have set to cv2.CHAIN_APPROX_SIMPLE, why the resulting contours contains more than 4 points? i noted that the drawing is correct as it perimeter along the square object but the fact it have more than 4 points puzzle me.
you probably misunderstood it
A contour is a boundary between two regions
bad edit, title and question no more match.
