I am looking for a way to identify all of the number plates/license plates in an image. I am not interested in reading them (i.e. OCR), only identifying the locations of them.

What techniques or algorithms would be useful in finding these? I am currently exploring some of the options available in OpenCV.

Thanks.

The size and colours of UK number plates are defined by law ..

I would search for the correct rectangular outline & colour …..(to optimize your algorithm I suggest using one of the ‘evolution’ techniques from AI).
