SIFT is not enough for this task. There are many computer vision researchers working on this application (automatically inferring location of an image), and accuracies are pretty low right now, except for popular landmarks. The problem is t

I find numpy too heavy weight for a lot of stuff and also not very good for communication/interchange with other programs. For a lot of my work, I often need to write data files to disk (for C programs to use) or mmap'ed files for concurren

Not just space, but speed as well. I've often noted significant speedups in many operations by switching to array.array. In some cases, the speedups are comparable to or even slightly better than using numpy (which is much more heavy-weig

Heh, I started reading this comment and was ready to jump on something I disagreed with, but remarkably we're in full agreement! Somehow I'm always surprised when two vision people agree on the right way to approach a problem =)

I'd say both are somewhat true. A lot of early "progress" in AI was found to not survive contact with the real world -- for example, most of computer vision. This was because collecting data was so expensive/difficult that only a few images

On the other hand, a lot of new research (including possibly ground-breaking theoretical results) are only possible now that we have access to large data. We might be initially processing the large data using relatively simple techniques, b

You probably can't go into any details, but can you describe the rough approach R-01 is taking? Is it based on some existing paper or something completely new?

Is there a collection of these kind of blog posts somewhere? i.e., for comparing the stacks of different sites?

This civilized, well-considered, thought-provoking back-and-forth is one of the reasons I fucking love this site.

I always cringe when I see math or programming or anything I know something about in popular media as it's usually done so poorly. So how badly did they butcher the concept of the Dirac sea for the episode? Of course it's all fiction anyway

Actually, I found it surprising because almost all theoretical economic models seem so divorced from reality that nothing ever works as you expect.

Not at all! I'd love for vision to be solved, no matter what the method. I'm more than happy to move onto another field if that's the case. But I don't think it is. MNIST data is not particularly challenging. It's great that deep learning m

by apu 15y ago
As a computer vision researcher, I'm not at all convinced that deep learning methods will be "final" in any sense. I know that in the past, neural networks were "final", and then graphical models were "final", and so on. And while deep lear

How much power/influence do a company's VCs have to prevent this sort of behavior? It seems like this reflects badly on all of Zynga's investors as well, most prominently Union Square Ventures, and I can't imagine that they would condone th

Mr Ritchie had more luck. “It’s not the actual programming that’s interesting,” he once remarked. “It’s what you can accomplish with the end results.” Amen to that, Mr McCarthy would have said. Uh, why would McCarthy have said that? That

Mr McCarthy has had less direct impact. That is partly because he believed, wrongly, that minicomputers were a passing fad Actually, on a long enough timescale, he might very well have been right. Of course users will still have many devi

Skimming through the API docs, it seems to be a very small subset of OpenCV at the moment. However, a lot of vision is how you handle the details (both for speed and for accuracy/performance). Without using it extensively, it's hard to say

I hate how this (and to some extend OpenCV) expect you to understand computer vision to use the library. I sympathize with your frustration, but being in Vision myself, I have an idea why this is the case: vision only barely works! What

Norvig's talk at Startup School '08 went into more details on this: http://www.youtube.com/watch?v=LNjJTgXujno They do use SIFT (or at least a variant thereof) for finding and describing interest points, but by itself, there is no geometr
