Open Cv Face Tracking Memory Issues
Mar 20th, 2008, 12:09pm  
Hello General Processing Brains,

I was hoping someone might be able to point me in the right direction about the following problem...

I'm trying to get the Face Detection Library working,  as provided by Jaegon Lee, through this site.

I'm running Intel Mac (OSX 10.4.11), and have successfully installed the OpenCV framework (I hope).  But when I open and run the provided example I get a memory error, and the Applet crashes.  It output's something like:

FaceDetect 0.2a
Invalid memory access of location 6d657473 eip=90a59398

So it seems to be happily returning the version, and therefore initializing.   A little more playing around revealed that the error seems to appear when trying to run the actual detection method (Faces = fd.detect();)

Also, to further confound things I can compile and run the Face Detection OpenCV Xcode project and get successful results: http://www.vimeo.com/688095

Any ideas on where to go next,  (or advice to just drop it) would be appreciated.  Thanks In Advance.  Dan.

I have the same issue, including the memory location.

Invalid memory access of location 69670000 eip=90a5a092

I seem to remember somebody did get it to work. Did you try the PC version? Seems a little better documented, I'll give it a try for sure.

BTW, is the low framerate in your video real or just from the video capture software? Because it seems pretty laggy.

I've been speaking with someone recently about their working version of the Face Detect plugin.  They sent over their working version,  which failed to run again on my mac.

The only difference we can see is the version of the OS.  Both the Face Detect example (cunningly gleaned from the image) and their example both ran in 10.5,  but I'm running 10.4.

What about yourself?
