Hi All:
I seen more examples to recognize line/circles/ellipse using Hough transform, but i didnt find examples for square or rectangles. Can anyone help me on this?
thanks.

You could look at this code on FileExchange, which appears to support triangles and squares:
It's been years since I did anything with the hough transform, but from memory if you want to find rectangles (or indeed ellipses) you need to search a range of possible width/height ratios or hard-code the width/height ratio that you are looking for. I think even with regular geometry like squares and circles you still need to specify a width/radius.
