Face recognition using OpenCV. On a single RPi, it's a hog, requiring all kinds of pipeline optimizations to get results in reasonable time. Combining concepts like SIFT with face recognition is impossibly slow. A cluster sounds like exactly the kind of thing that would help. Since the examples you've given are already related to image/video processing and since OpenCV is C++, you may find it a good fit. Put a camera on your doorstep, install your cluster, let it recognize your family members, and charm them with a welcome :)
