Dear all,

I've just started learning Pd. I would like to program something that's probably too complicated for me, so I could really use your help in giving me some pointers.

Basically I want to create a video version of the mona lisa: there is a face on a monitor that appears to look you in the eye from far away, but when you go closer the eyes seem to turn away to the side.

Let's say you use a computer monitor for this.

First step:
I was planning to use the built-in webcam as a device to measure how far somebody is from the camera, for example by how many pixels are changing.

Possible disadvantage: it doesn't take into account how many people are standing in front of the camera (maybe a lot of them are standing far away). A possible way to deal with this is to take into account the vertical distribution of the pixel change.

Is there already an object that uses the webcam to output this kind of data? Or is there an alternative to reach the same goal?

Thanks!

what about using something like autoCV to detect faces, and sending a signal to pd that way?

im also new, but ive seen some cool things done with face detection programs.

theres also face osc, or facetracker
