body: <p>I am trying to subtract the "hue" part of an image from that image.I have extracted all the h,s,v components .But i do not  know what to do next?Is it even possible??</p>
  
  <p>Here is my code</p>
  
  <pre><code>import cv2
  
  def showimage(text,img):
      cv2.imshow(text,cv2.resize(img, (700, 700)))
      cv2.waitKey(0)
      return 0
  
  
  # Read image in BGR
  img_path = "new.jpg"
  img = cv2.imread(img_path)
  showimage("orig",img)
  # Convert BGR to HSV and parse HSV
  hsv_img = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)
  showimage("hsv",hsv_img)
  h, s, v = hsv_img[:, :, 0], hsv_img[:, :, 1], hsv_img[:, :, 2]
  showimage("h",h)
  showimage("s",s)
  showimage("v",v)
  
  sub=hsv_img-h
  cv2.destroyAllWindows()
