square detection enhancement

I am developing a currency identification system for blind people. I need to check if the full currency note has been captured so I used square detection for that. It is currently working when the background is pure black or white, but not when the background is more advanced. What techniques can I use to solve this problem?

I am using OpenCV as my image processing framework. Can I use convolution? How?

need enhancement for square detection.

Result image of my code:

I am not sure whether rectangle detection is the best solution for what you want to do.

It will only work efficiently if the picture is taken right up from the money, and as you say will not be robust to cluttered backgrounds.

Is there a precise reason for not going to a direct pattern recognition system ? I'd start with a picture of my currency and try to perform object recognition with it.

You will find loads of tutorials that can help you on the web, like for bottles or for bowls.

You might have a lot of possibilities, due to the number of currencies but you know it to be a finite number at least.
