title: How to get x,y coordinates using python?
body: <p>I have detected the corners (red dots in the image) of this image using below algorithm (cornerHarris). Now I want to get the coordinates of that points. How can I do that?</p>
  
  <pre><code>import cv2
  import numpy as np
  
  filename = 'Square.jpg'
  img = cv2.imread(filename)
  gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
  
  gray = np.float32(gray)
  dst = cv2.cornerHarris(gray,2,3,0.04)
  
  #result is dilated for marking the corners, not important
  dst = cv2.dilate(dst,None)
  
  # Threshold for an optimal value, it may vary depending on the image.
  img[dst&gt;0.01*dst.max()]=[0,0,255]
  
  cv2.imshow('dst',img)
  cv2.waitKey(0)
  cv2.imwrite('CornerSquare.jpg',img)
  </code></pre>
