Details about calculating the mean about superviseddescent HOT 1 CLOSED

Hi Marko,

Thanks for the praise!

First of all a small detail: the mean and median are not the same, I adjusted the title.

Calculating the mean face is really not that interesting or important, so don't think too much about it! In the simplest way, it's really easy: You can just average all landmarks. Without normalisation or anything. Just load your 100 files, and average each landmark's x and y over all 100 landmarks. You can directly plot that result, for example with OpenCV or Matlab, and it has to look like a mean face. It's really too easy to even give sample code! It's just loading all x and y's and calling cv::mean() or you can also do it in Matlab. What you can do after is for example rescale the points to (-0.5, 0.5) x (-0.5, 0.5) - I think I did that.

You can do more fancy stuff like Procrustes before averaging but it's really not worth spending time on it.

I hope that helps!
