ocrtxt.Text is not working?

I tried text extraction from http://in.mathworks.com/help/vision/examples/automatically-detect-and-recognize-text-in-natural-images.html. its working fine. but the last line ocrtext.text does not show the result. it is empty. what to do to extract the result (ie. detected text)

Hi Brindha,

Are you running the example as is, or are you trying it out using a different set of images?
