title: BGR values of masked image (OpenCV, Python)
body: <p>Using the follow image..</p>

  <p>... I am applying this code to create a circle mask:</p>
  
  <pre><code>import cv2
  import numpy as np
  
  img = cv2.imread("car.png")
  
  height, width, depth = img.shape
  circle_img = np.zeros((height, width), np.uint8)
  
  mask = cv2.circle(circle_img, (int(width / 2), int(height / 2)), 90, 1, thickness=-1)
  masked_img = cv2.bitwise_and(img, img, mask=circle_img)
  
  cv2.imshow("masked", masked_img)
  cv2.waitKey(0)
  </code></pre>
  
  <p>This is the output..</p>

  <p>How can I find BGR values of the circle using OpenCV ?</p>
