Web1 answer. there are some differences between the opencv3 and opencv2.4 bindings, - with the 3.1 ones, the drawing calls like cv2.circle, cv2.rectangle or cv2.polylines return a new image , but the 2.4 versions do not. so, in your case, cv2.polylines returns None, and you're trying to imshow () an invalid/empty image. OpenCV expects that imshow () will be fed with BGR color space so you need to convert whatever image into BGR before displaying. You already had the BGR image, so you don't need to convert it to HSV to display it. The only time that the image will be truly changed is when you convert it to grayscale. fivem take hostage script https://dearzuzu.com
