title: Detecting decimal points using OpenCV
body: <p>Using <code>opencv-python</code>, I'm trying to find the location of <code>dot</code> characters in images similar to this one: </p>
  
  <p><a href="https://i.stack.imgur.com/8LoUu.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8LoUu.jpg" alt="enter image description here"></a></p>
  
  <p>42 images set here can be seen found here: <a href="https://imgur.com/a/i4GPQwE" rel="nofollow noreferrer">https://imgur.com/a/i4GPQwE</a> - Bulk download available</p>
  
  <p>I cant create an <code>opencv</code> detector that can consistently find most of the dots in those type of images, whatever works on a single image (blob detector with some parameters) usually fails on other images.</p>
  
  <p>Most of my tries were around using <code>SimpleBlobDetector</code> is it the right approach?
  Is opencv not the right tool for the task? (I need a ready to use tool, training a neural net is not possible at the moment)</p>
  
  <p>Your help is appreciated.</p>
