Hi Folks,

As my platform have limited resource, such that i cant put the entire OpenCV in it.

Actually it is no OS there. Can you suggest how to do the Hough Transformation there?

I already got a edge image in the memory by a stand alone canny edge detection, but i am not sure how to proceed on....

Any pointers?

Regards, Ajay

anything hough based is terribly expensive, and there's no builtin way to detect rectangles like this.

rather try to find alternative means.
