Looks like more evidence for Atwood's Law: Any application that can be written in JavaScript, will eventually be written in JavaScript. I have a couple of questions: 1. How does Liu Liu's algorithm (which I think he calls "deformable parts model") compare with Viola-Jones [1]? Any idea what the error stats (false positives & negatives) are like? In my experience [2] Viola-Jones has very low error rates. Regarding per…

Liu Liu's code is a javascript port from openCV I think. As far as I know it is an implementation of Voila-Jones.

Try this in the page: $('#detect').click(); setTimeout(function() { $('.face').prepend(' http://officialpsds.com/images/thumbs/Santa-Hat-psd20202.png width="90px" />'); $('.santaHat').css('position', 'relative'); $('.santaHat').css('top', '-60px');$('.face').css('border-width','0px'); }, 200);

replace:

  src="http://officialpsds.com/images/thumbs/Santa-Hat-psd20202.png width="90px"
with

  src="http://officialpsds.com/images/thumbs/Santa-Hat-psd20202.png" width="90px"
and it's perfect

Earlier quoted context omitted.

The author credits Liu Liu for the algorithm

It's not just the algorithm, the whole detection code is just cutpasted from liu liu's repository. https://github.com/liuliu/ccv/blob/stable/js/ccv.js

The sheen is coming off this quite rapidly.

Thanks for the correction!

Corrected version:

$('#detect').click(); setTimeout(function() { $('.face').prepend('http://officialpsds.com/images/thumbs/Santa-Hat-psd20202.png width="90px" />'); $('.santaHat').css('position', 'relative'); $('.santaHat').css('top', '-60px');$('.face').css('border-width','0px'); }, 200);

So what did this new library do other than wrap this algorithm with a redundant jQuery plugin?

Still missing a quote here... There is a missing quote before width= I tried posting the full code, but HN seems to remove it.
