import cv2

a1=cv2.VideoCapture(0)
while True:
s,frame = a1.read()
b, g, r = cv2.split(frame)
zeros_ch = np.zeros(frame.shape[0:2], dtype="uint8")
red_img = cv2.merge([zeros_ch, zeros_ch, r])

c= red_img.mean()
print(c)
# plt.plot(c)
# plt.show()
if cv2.waitKey(1) & 0xFF==ord('q'):
    break

a1.release()
cv2.destroyAllWindows()
