I've been playing with vision processing stuff for the XO, mostly using OpenCV. I have some sample code up at http://eclecti.cc/code/face-detection-on-the-olpc-xo that does face detection surprisingly quickly. It seems that the bottleneck isn't even the OpenCV Haar Cascade algorithm, but the time it takes to initialize the v4l2 drivers.
The code I wrote is just basic proof of concept stuff, but there are some amazing possibilities involved in vision processing, like recognizing sign language and gestures, drawing in air, playing motion based games, and even identifying plants and wildlife. If anyone is interested, I'd like to start developing an Activity that uses face/object detection for something more fun or useful. I'm new to Python and OLPC development, so I could use some help. Alternately, I am a student, so if anyone is interested in mentoring this as a possible Summer of Code project, that would be great. _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
