title: Python OCR: ignore signatures in documents
body: <p>I'm trying to do OCR of a scanned document which has handwritten signatures in it. See the image below.</p>
  
  <p><a href="https://i.stack.imgur.com/ihLnJ.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/ihLnJ.jpg" alt="enter image description here"></a></p>
  
  <p>My question is simple, is there a way to still extract the names of the people using OCR while ignoring the signatures? When I run Tesseract OCR it fails to retrieve the names. I tried grayscaling/blurring/thresholding, using the code below, but without luck. Any suggestions?</p>
  
  <pre><code>image = cv2.imread(file_path)
  image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
  image = cv2.GaussianBlur(image, (5, 5), 0)
  image = cv2.threshold(image, 0, 255, cv2.THRESH_BINARY_INV | cv2.THRESH_OTSU)[1]
  </code></pre>
