How to set HSV color range in OpenCV?
问题 I have a phone and it's HSV histogram like blow,and I want to track this phone's movement.Based on it's histogram,I set image range like this: greenLower = (300, 0, 50) greenUpper = (50, 128,250 ) cv2.inRange(hsv, greenLower, greenUpper) But nothing got detected out when waving the phone,and I am pretty sure it is because color range is wrong,would you tell me how to get color rang setting right?Especially,when HUE values are between [300~50],should I set it to (50~300) or (300~50) due to HUE
