Nice site. I saw this project and knew it had to be eigenfaces: https://devart.withgoogle.com/#/project/16569221 https://devart.withgoogle.com/#/project/1656922

Eigenfaces is a very old technique for doing this (it was old when I implemented for the first time in 2000) and as you can see the results are rather blurry. It only takes about five lines of code in a matrix language -- collecting data was the main issue I recall.
If nothing else this serves as a good example of the value of framing your work. Done in a machine learning / stats context eigenfaces is not much more than a nice blog post (e.g. http://jeremykun.com/2011/07/27/eigenfaces/ http://jeremykun.com/2011/07/27/eigenfaces/) or class project. But ... present it as an art project and you get frontpage on Google's new site.
- m-photonic 12y agoVery interesting. What if you took a large set of musical notes on various instruments, with about a two-second duration, with the same pitch, same volume, and same sample rate, and did the same thing? Eigensounds! And that's just with a time-domain representation of the sound -- you'd get different eigensounds if you used a frequency-domain representation. I have to wonder if something like this is used by those song-recognizing apps that can tell you what a song is just by hearing a snippet through your phone.
