Combining colors and outlines to produce a cartoon

The last step is to combine the two previously achieved effects. Simply fuse the two effects together into a single image using cv2.bitwise_and. The complete function is as follows:

def cartoonize(rgb_image, *,               num_pyr_downs=2, num_bilaterals=7):    # STEP 1 -- Apply a bilateral filter to reduce the color palette of    # the image.    downsampled_img = rgb_image    for _ in range(num_pyr_downs):        downsampled_img = cv2.pyrDown(downsampled_img)    for _ in range(num_bilaterals):        filterd_small_img = cv2.bilateralFilter(downsampled_img, 9, 9, 7)    filtered_normal_img = filterd_small_img    for _ in range(num_pyr_downs):        filtered_normal_img = cv2.pyrUp(filtered_normal_img) # make sure resulting image has the same ...
