Facial recognition system
 

I don't know why, but I just thought about a facial Recognition System software. I'm wondering what would be involved with such a system? I have the basic Outline of:
Input:
Picture to verify
Output:
If the person is found in the database.
Processing:
Detection of the different facial parts
Comparing the widths of different facial parts such as eye to eye, eyes to nose, mouth width, mouth to eyes, etc. Using ratios to compare a smaller picture to a bigger picture.
What Language would you suggest, I am thinking C++.
What database system would you suggest?
Do you think there would/should be any AI involved with the recognition system?

learn math. lots of math. i suggest linear algera to start with.

If you're going to try to characterize a face by dimensions, you'll want to look into building a number of filters. For example, conversion to grayscale, sobel (or some other form of) edge detection, grabbing a histogram and normalizing it, or increasing contrast, etc. You can have more fun playing with that for a while, picking up whatever math you're missing as you go, than just doing a year's worth of reading on pattern-recognition all at once.

I would also suggest fractal trees would be quite useful.
