FYI Eigenfaces was a ground-breaking theory when introduced...almost 25 years ago. It's no longer used in any serious way for practical face recognition applications.

So back when I was a PhD student, we had an idea for a Captcha system that would be better than the current system and all alternatives by quite a margin, but we talked to some experts in the area, and they said that none of this matters be

It continues to function as-is (albeit with no updates) regardless of whatever happens to the company, right? And if it really is as useful as people are saying, on email, which most people spend hours of their day on, then I'd definitely s

That's far into the realm of sci-fi for now, given that basic face recognition is still quite poor. See my other comment for details: http://news.ycombinator.com/item?id=4275921

Terrible, unless you're in a "cooperative" setting, i.e., where the user is in controlled lighting conditions and looks directly at the camera, in a decent-to-high res photo. Labeled Faces in the Wild (LFW) is the de-facto standard for look

For 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 th

I'm a little late to the party, but super-resolution is a topic of interest in computer vision, and this approach is one of many that have been recently proposed. At a high level, I should say that the field is still searching for the right

I actually purposely used to set all the various clocks at home ahead by anywhere from 0 - 15 minutes. At first, I could remember which ones were ahead by how much, but then soon I started to forgot and had to just assume they were running

The Viola-Jones algorithm and Haar-like features are really only suitable for faces. Solving object detection/recognition for general classes of objects is one of the largest open problems in computer vision and thousands of researchers aro

Data size is indeed one of the key factors to consider when building vision systems, and in this respect, the current champ is Image Net: http://image-net.org/ They have images labeled according to the WordNet ontology, and the dataset is

For those who're looking at implementing a similar service, you should first start by looking at this project from researchers at UC-Irvine: http://www.ics.uci.edu/~xzhu/face/ This work was just presented at the Conference on Computer Vis

Yes, there is growing evidence that gamification, if done right , can be really good for teaching ideas. Zoran Popović [1], a faculty member here at the University of Washington, has been working on these issues for a few years now with hi

I was wondering the same thing. With a precomputed voronoi diagram and only a few hundred cells, lookups should be almost instantaneous.

Isn't it so disappointing that on all of your comments on HN, you are consistently discriminated against and censored? I mean, it's obviously done because of the politically correct anti-intellectual crowd on HN, whose only recourse is to w

To lend some credence to these claims: other than the well-known Sebastian Thrun, Google also has at least a dozen world-class computer vision researchers working on a variety of different products, from Maps to the self-driving car to Go

I looked at this briefly, and it would be extremely tough. Very few events have the kind of coverage (i.e., number of input videos) you would need to even get started on the problem. Plus, the conditions are just about the worst possible --

This looks like an incomplete page, or perhaps a work in progress. Which method was used for generating each mesh? How many input images were there? What do they look like? What's the takeaway message?
