Hough Transform for rectangle

Hi All,

I am a amateur playing around with hough transform developing in
vb.net. I have managed to create sub-routines to extract lines and
circle from reading articles in the net. However, I can not seem to
find a good article on extracting rectangle from image with hough
transform. Can anyone point me to a good article or example of
implementing?

Thanks.

Jonathan
