Convert BGR and RGB with Python, OpenCV (cvtColor)

http://www.iotword.com/5677.html WebThere are more than 150 color space conversion codes available in OpenCV. Some of the color space conversion codes are cv2.COLOR_BGR2GRAY, cv2.COLOR_BGR2HSV etc. The cvtColor () function returns the image with changed color space. Examples Let’s discuss examples of OpenCV cvtColor. Example #1 WebRGB[A] to Gray: Y = 0.299*R + 0.587*G + 0.114*B and Gray to RGB[A]: R = Y, G = Y, B = Y, A = max(ChannelRange) The conversion from a RGB image to gray is done with: bwsrc = cv.cvtColor(src, 'RGB2GRAY'); More advanced channel reordering can also be done with cv.mixChannels.
