Face Detection and other Vision Processing (and some sample code)

2008-03-20 Thread Nirav Patel
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

OpenCV has a Python API that uses SWIG. It's in the default fedoro repo as opencv-python. Good idea, I'll add it to the wiki momentarily. On Thu, Mar 20, 2008 at 6:47 PM, Chris Hager [EMAIL PROTECTED] wrote: Nirav Patel wrote: I've been playing with vision processing stuff for the XO

I don't know about integrating it into Record, but the other issues are fairly easy to resolve. I wrote a Python module over the summer to interface v4l2 cameras that returns Pygame surfaces. Capturing images is near instant (~20ms for 640x480 RGB). Autogain and autowhitebalance can be disabled

My roomate and I wrote an auto-stitching Panorama Activity during the Yahoo Hack Day at CMU yesterday (ended up winning the Hack for Good award). I'll be posting it in the wiki at some point today. It needs a whole lot of polishing, since it was written in 24 hours. I ran into the same problem

That sounds like a much better idea. I'll try to set up something like that on my webserver, though I'll have to move elsewhere if the activity gains any kind of popularity. It still leaves the problem of the images uploading to my personal Flickr account though. I think having a Panorama

Chris, We're working on switching from gstreamer to the pygame camera module. Gstreamer in 8.2 had some changes that broke the pipeline Colors was using. While it would have been possible to change the pipeline, switching to pygame will be easier/better for both the videopaint and photo snap

1) Are there any existing hooks/systems for Linux for multi-touch? That's the only proper way you can get a virtual keyboard to work for a double-touchscreen clamshell device (the feasibility of which is not sold to me because of the power consumption of running a 2nd screen vs a keyboard,
