Although not actionscript specific, I recommend having a look at the MPT library. Hopefully you could write a wrapper using Alchemy and use that.

If it helps, you could download openframeworks and start prototyping. We had Computer Vision workshop and you could get samples for blink and smile detection from the OF Wiki
