# here is my python code:
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
gray = cv2.bitwise_not(gray)
top = int(0.25 * gray.shape[0])
bottom = int(0.25 * gray.shape[0])
left = int(0.25 * gray.shape[1])
right = int(0.25 * gray.shape[1])
gray = cv2.copyMakeBorder(gray, top, bottom, left, right, cv2.BORDER_CONSTANT, value=255)
kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (2 * 5 + 1, 2 * 5 + 1), (5, 5))
res = cv2.dilate(gray, kernel)
