Face detection and multiple camera feed's

Today set up an tested 3 webCam simultaneously with Opencv to confirm it can handle multiple feeds, there seems to be a small delay while it is running (I can watch myself blink) but its not huge.

Also tried out the Face detection using Haar-like feature detection example that comes with opencv, this worked but was slow,the camera feed seemed to stutter and very gradually grow out of sync with realtime leaving a lag of a few seconds.

I think this may be because it is checking every single frame it receives for faces,it also takes half second to check most of the time, and occasionally  will  pick out items that do not even appear facelike. Training my of Haar classifier might be a good idea.

OpenCv very easy setup

Seems setting up and using Opencv even with multiple video feeds is very easy, though using multiple feeds seems to make it run a good bit slower.

Doing this only took a few lines of code

Started working with opencv(aka learning very slowly)

Tried out an example for an O'reilly textbook, seems the textbook despite being fairly new is already little outdated  cvloadimage requires a minimum 2 arguments to be used as opposed to simply a file address.

oh well least im over the hurdle of getting the sdk to work
