title: How do I use Emgu CV to detect arrows in an image?
body: <p>I am doing some basic image processing to detect polygons and a bit of OCR to process a flow chart drawn on white boards using Emgu CV on C#.</p>
  
  <p>But now, I am facing difficulties <b>detecting arrows</b> (straight lines with a pointed &lt; or >) in any direction.
  I am wondering if anyone is aware of a method that I can use to detect arrows and their <b>pointing end</b>. From then, I can find nearby objects and go ahead with more processing.</p>
  
  <p>I would <i>greatly</i> appreciate any suggestions anyone might have.</p>
  
  <p>Thank you!</p>
