Recently I stumbled upon an interesting open source framework called OpenALPR (Automated License Plate Recognition). This seemed very interesting for trying out on the Raspberry Pi. The OpenALPR framework has a couple of dependencies that you have to download and compile first.
Recently I have received the Raspberry Pi, Model B. I wanted to try out the OpenCV framework on the Pi. After installing OpenCV and all dependencies I tested something similar to iOS OpenCV Sample I wrote a while back. The project shows detection of a yellow circular shaped objects, face and smile detection. The code is written in Python. With Raspberry Pi I have used a low cost usb web camera I had lying around.
