Take a look at Francis Bacon's Novum Organum written in 1620, specifically the sections on the four idols of the human mind that sometimes prevent one from reaching truthful conclusions. To my mind, this is philosophy of science befor

Mean shift clustering, for one. This short PDF provides better insight than wikipedia. Does NOT require you to specify the number of clusters like in K-means: http://homepages.inf.ed.ac.uk/rbf/CVonline/LOCAL_COPI

I'm curious what particular claim you think Hofstadter is pushing that is unwarranted -- I don't see how a book of wandering musings could earn the label "pseudoscience" when it doesn't claim to be scientific in the

After you're done reading GEB, I highly recommend moving on to the rarely mentioned "The Mind's I", Hofstadter and Dennett's 1981 collection of essays and stories about self/mind by themselves, Alan Turing, Ric

I couldn't, for the life of me, figure out what it was they had printed until you said it was a ship (upside-down of course). The best I could come up with was the flying spaghetti monster. I guess they're showing delicate things

Thanks for trying out the app, and we really appreciate the feedback. It's definitely not the 5S camera, which we've tested with extensively. The best scenes to capture are those with highly textured objects at different depths i

One of the developers here, and thanks for the feedback -- that's a pretty good guess at what we were going for. It looks like this dropped off the new page pretty quickly but thanks for taking a look!

Agreed, what it made me really stop and question is why we DON'T do this with smartphones already and it's because there is no fixed base relative to which we can twist/nudge the screen (as well as a smartphone being too big

I'll take a stab at this (I'm a decade out from my last machine learning class, so no guarantees on correctness): The only reason it's fitting a hyperplane is because one class is being mapped to the continuous value -1.0 and

Interesting point. I wonder if arcades, bowling alleys, and roller rinks all followed the same trajectory. My local bowling alley actually had an extensive arcade in the late 80s to mid 90s. You'd go for the bowling and stay for the Cr

It sounds like maybe you're describing AirPlay mirroring instead of passing the video stream straight to the Apple TV via AirPlay from an iPad or iPhone. Mirroring has to re-encode the on-screen video on the fly, so I've seen the

Thanks for the explanation! I've spent so long using the aforelinked diagrams to visualize how much light falls onto a surface that thinking about gravity that way brought up a few bizarre possibilities. Thanks for clearing things u

I had somehow never made the connection that the gravitational inverse square law has the same physical explanation as visible light fall-off [1] -- energy being distributed over a larger area with increasing distance from a point source (w

That gave me pause too, and this is the best explanation I could think of for why the author brought it up: The anthropic principle can explain why we find ourselves in a universe exactly this old, because billions of years earlier the cond

I share your viewpoint but I think there is a potential solution to this problem (not that I advocate doing it, treat it as a thought experiment): implant the blank slate hardware for the digital copy years before it takes over everyday ope

In some ways, yes, though while the approach you describe has been explored ( http://www.inf.ethz.ch/personal/ataneja/ModelingDynamicScene... ), that's not quite what concentric mosaics and other light field

by GrantS 13y ago
The solution is to use a multi-camera array (not just stereo) to capture as much of the light field as possible and then re-synthesize stereoscopic video from the user's viewpoint by grabbing pixels located along the appropriate rays.

This is a nice idea -- the biggest practical problem would be motion blur while the cameras are in flight. If thrown straight up, there's a moment of zero motion at the top that mitigates that problem, but it's still an issue the
