WebThere are more than 150 color-space conversion methods available in OpenCV. But we will look into only two which are most widely used ones, BGR Gray and BGR HSV. For color conversion, we use the function cv2.cvtColor (input_image, flag) where flag determines the type of conversion. For BGR Gray conversion we use the flags cv2.COLOR_BGR2GRAY. http://duoduokou.com/python/26378304631793491082.html
