title: JavaScript text recognition and OCR on <canvas>
body: <p>I found a web application that recognizes handwritten math equations:</p>
  
  <blockquote>
    <p><a href="http://webdemo.visionobjects.com/equation.html?locale=default" rel="noreferrer">http://webdemo.visionobjects.com/equation.html?locale=default</a></p>
  </blockquote>
  
  <p>I would like to know if someone knows an app or a tutorial or an open source project that implements this mechanism, because getting it from this webapp is really complex.</p>
  
  <p><strong>Note:</strong> I just need the equation drawn in the canvas to be translated in an input text box that's all. </p>
