对于各种色彩空间的变化，opencv 都给我我们相应的接口，直接调用即可，下面我们来看一下：

def color_space_demo(image):
    #  trans to gray
    gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
    cv2.namedWindow('gray_space', cv2.WINDOW_AUTOSIZE)
    cv2.imshow('gray_space', gray)
    # trans to hsv
    hsv = cv2.cvtColor(image, cv2.COLOR_BGR2HSV)
    cv2.namedWindow('HSV_space', cv2.WINDOW_AUTOSIZE)
    cv2.imshow('HSV_space', hsv)
    # trans to yuv
    yuv = cv2.cvtColor(image, cv2.COLOR_BGR2YUV)
    cv2.namedWindow('YUV_space', cv2.WINDOW_AUTOSIZE)
    cv2.imshow('YUV_space', yuv)
    # trans to Ycrcb
    ycrcb = cv2.cvtColor(image, cv2.COLOR_BGR2YCrCb)
    cv2.namedWindow('Ycrcb_space', cv2.WINDOW_AUTOSIZE)
    cv2.imshow('Ycrcb_space', ycrcb)

    return 0


img_path = os.path.join(os.getcwd(), 'yao.jpg')
my_img = cv2.i
