256 Shades of Gray [pdf]
- dfc 14y agoI love the arsclassica latex style! http://www.ctan.org/tex-archive/macros/latex/contrib/arsclassica/ http://www.ctan.org/tex-archive/macros/latex/contrib/arsclas...
- hsmyers 14y agoShhhhhh! Remember the comment about Riff-Raff :)
- dfc 14y ago???
- mertd 14y agohsmyers is referring to the first sentence in the linked pdf. Parallel machines are hard to program, and we should make them even harder – to keep the riff-raff off them. — Gary Montry
- dfc 14y agoThanks mertd. Can you explain what this has to do with my latex comment? I was not supposed to describe the magic behind the typesetting/layout?
- galaktor 14y agoI believe hsmyers was jokingly trying to say that it would suck if everybody ("riff-raff") started using that template going forward, rendering it "normal", hence not special anymore.
- flog 14y agoThanks! I had just come here to ask about the typesetting on this... it's pretty lush. Good job.
- revelation 14y agoThats cool, but it seems to have the performance equivalent of an early P4. Theres talk about FPS, but then its mostly about static images?! Theres little information about the actual performance of the system on the FPGA because everything is seemingly hamstrung by the woefully inadequate AVR used for feeding the data.
- CamperBob2 14y agoSheesh. It's an undergrad term project. They're not trying to line up an IPO.
- hucker 14y agoWe didn't really do any benchmarks that would permit me to actually say it has the performance equivalent of anything, but I was probably not alive when the last "equivalent" system was made. This was purely an educational endeavor. There was much talk about the FPS because the class had to separate groups with the same assignment, one was to focus on energy efficiency, and the other (us) on performance. And yes, the AVR proved woefully inadequate as you point out, but we were required to use it so not much we could do there. The project was loads of fun (and work!) anyways, and it was great to be able to put theory into practice for once :) If anyone have any questions regarding the project I'd be happy to answer them by the way.
- starefossen 14y agoThe 256shadesofgray.com website is currently work in progress. There will be more details and stuff there soon.

- ars 14y agoThis submission needs a better title.
- starefossen 14y agoYes, the name of this project is "256 Shades of Gray" – with an 'a' instead of an 'e' in Gray.
- thwest 14y agoAm I the only one that is dissatisfied with all of the Lena references in the computer vision community? For a few years I was righteously indignant about the gender issues involved but now it's just trite. Makes us seem like adolescents that we find it so important to reference a Playboy photograph.
- confluence 14y agorolls eyes It's just a standard image of a woman wearing a hat that has a lot of dynamic colors and allows people to check and compare graphic transforms easily - there is nothing offensive about it. Unless, of course, you find colorful pictures of women wearing hats offensive.
- StavrosK 14y agoErm, you might want to take a look at this (NSFW): http://www.lenna.org/full/len_full.html http://www.lenna.org/full/len_full.html
- CamperBob2 14y agoExcept that's not the complete story, is it? The complete story is that Lenna is from a culture where nobody makes that big a deal out of human sexuality, and that she was surprised and "pleasantly amused" when she learned of her indirect contribution to image processing technology.
- StavrosK 14y agoI'm just pointing out that the photo is more than the headshot. My culture doesn't make a big deal out of human sexuality either, and, as for the sexism issue, I'm not touching that with a ten foot pole on HN, because any opinion with the word "woman" in it somehow turns out to be sexist (probably including this one).

- contingencies 14y agoTo the implementers: congratulations on a successful project, but please make sure you consider the ethics of your field before applying what you have learned for money.
- politician 14y agoAn enjoyable paper, a thoughtful example of engineering under constraints, and a successful outcome. Congratulations! (But, and I'll gladly take the karma hit for saying this, please don't pay any attention to my fellow HNers complaining about every possible tangential non-issue.)
