White on the face is less common but it does occur. im_lab = cv2.cvtColor(im, cv2.COLOR_BGR2LAB) l = im_lab[:, :, 0] L2_mean = np.mean(l) L2_std = np.std(l) if L2_std != 0: l = (l - L2_mean) / L2_std * L1_std + L1_mean l = l[:, :, np.newaxis] im_lab = np.concatenate((l, im_lab[:, :, 1:]), axis=2) im = cv2.cvtColor(im_lab, cv2.COLOR_LAB2BGR) im *= 255. If you are not noticing much of an effect, try scooting in the endpoints of the A and B channels a little bit more (say, down to 80 if you are using the input numbers). CIEDE 2000 is a major revision of CIDE94. 3. hi I’m new to labs and there babies.I have a cream female and a black male what colour babies might I get?? advance to the next slide.
