The inherent assumption on which chroma sub-sampling is founded is that luminance information is far more important than chromanance information. This is backed up by empirical evidence. From there, the effect follows directly from the equa

I did a little research to make sure he was right, and I've convinced myself that he is, so I've added an update at the top to correct it.

Our algorithm is also not a "face detector". It's a feature-based machine-learned image classifier that was trained on faces and non-faces. However, when speaking to those presumably without a background in machine learning, I think "face d

1. Write a list of the things you need to do. Be detailed. The more detail, the better. 2. Estimate how long you think each will take, knowing it always takes longer than you think. 3. Realize it always takes longer than you think, and revi

I got bad news. The question was to find the distance between a point and a line SEGMENT. Luckily, since you know some math, and you understand what a dot product is, and how it relates to a projection, you can trivially extend your solutio

This is bordering on semantics. What's the difference between mathematical inclination and logical inclination? The field of computer programming has made a separation in alot of people's mind that simply didn't exist before. People, especi

First, Jeffs view of programming is too narrow. Secondly, and more importantly, so is his view of math. Being "mathematically inclined" does not mean being well educated in mathematics. You don't need to be able to rigorously prove the fund

There is no "think". There is "do" and "do not". Sounds like you've made your decision and you just want a push. And since you've asked here, instead of anywhere else, you know that we will push. And that's what you want. You are just a tin

This is a false dichotomy. Having the interviewee give a brief talk and following with a dialogue about something they've worked on in the past is absolutely vital. An interview consisting of that exclusively is probably better than an inte

Recognition is generally broken down into two steps, processing faces into "templates" and then comparing those templates. Generating templates includes all the preprocessing stuff as well: detecting faces in an image, estimating their pose

I have a few comments for you guys about our demo: 1. Image to Image is a bit misleading because we are fairly strict in our online demo in pose requirements, so many faces are "non-suitable" because they aren't frontal. 2. It works much be

axod's too shy to post his own good news, but even bigger (in my opinion) news: mibbit will become the default irc:// handler in Firefox. I have to admit that irc:// links are pretty rare, now, mostly due to how unreliably they work. Big us

Here's my initial concerns, reading your post and reading your posting on craigslist. You need avoid looking like a business guy with an idea (and without a clue) looking for a coder. I'd work very, very hard to avoid that because technical

The short version: the file system got corrupted. The backup was just a file-sync over a firewire network to another machine. Meaning the bad data was backed up and presumably overwriting the older, good data. They had a RAID but the proble

Let me start by saying that your post seems sincere, but I believe extremely misguided. I'm going to post my thoughts, in detail. I'm sorry but I'm going to have to ignore your assertion that I decided it was "satire" retroactively. That's

I think you'd be hard pressed to actually make the case that my post represents an appeal to authority. I've read it again and again and the only way I can see that interpretation is if someone didn't actually bother to read it fully. Eithe

As stated, you can do the exact same thing in linux for ada as you can for python. As for AdaCore, you've gotten sidetracked onto their dual-licensed (and costs-real-money) compiler. The free stuff is at: https://libre.adacore.com/

That's pretty much complete nonsense. First, the premise of the article is that people bring false expertise and unfounded certainty to the topic at hand. That has pretty much nothing to do with the veracity of various youtube videos, or MS

Alright, at the bottom of this thread is a downmodded discussions about macroeconomics (started by someone who read only the last paragraph of my post and decided to argue with me about my facetious assertions). Last week, there was a post

Author here. First, I did say, but perhaps not strong enough, that I include myself in the list of people who do not what they are talking about (or, more properly, in the group of people that do not have strong opinions). I’ve done a fair
