Nice idea, it might find some quirk of the face detector though, and exploit that, instead of producing a truly face-like image.
On the other hand, I vaguely recall a talk by VS Ramachandran where he claimed that in essence that's what Picasso and many others did also, i.e., you might see a painting that objectively doesn't strongly resemble a face, but it hits the right spots in your brain's face detector, so your brain says to itself "now that's what I call a face". A bit like how colorful candy triggers "ripe fruit - eat it!".
- apu 14y agoFor the standard Haar-based Viola-Jones detector, all the parameters needed for it to say "yes" to a detection are known ahead of time if the detector is already trained. They consist of adding and subtracting different rectangles within the image and comparing the sum to a pre-defined threshold (this is called a "weak classifier" in this context). This is done for ~30-50 different weak classifiers and if all of them pass, then a face is declared there. Therefore, it should be relatively easy to find a set of rectangles that would satisfy these conditions. My guess, from having worked with face detectors for quite a while, is that it wouldn't be nearly as cool as what painters do -- the false detections would be more mundanely like faces, or so completely off-the-wall if they happen to be a pathological case.
- smackfu 14y agoYes, it seems to produce things that look like the noise that is accidentally marked as faces in current software. Which could be kind of neat actually... you could train it to look for Jesus for instance.

- BHSPitMonkey 14y agoA photo with a face on it is most often just creepy. A photo with some vector, monotone noise like this webapp produces could look kind of cool.
