Given a image with a rectangular flash light, I want to be able to detect the flash light
I'm trying to find a way to detect rectangle, but I'm lost.
If somebody can give me brief step-by-step pointers or advice as to how to approach this problem, it's be appreciated.
Thx in advance!

I think you can use Hough transform for the said purpose

Perhaps corner(), hough(), houghlines(), or else do a web search for "CBIR".
