opencv is grayscale code example
Example 1: convert image to grayscale opencv
img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)
Example 2: cv2.cvtcolor grayscale
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
