    Color Image Processing Paper Needed

    That isn't helpful at all. I'm well aware of that site, the paper isn't on it. I'd think that's generally the first place people look when they need a paper.

    Color Image Processing Paper Needed

    I'm trying to digest a chapter in a text that cites this paper as a source. The part where it talks about what this paper addresses is pretty poorly written, so I was hoping to get the paper itself. The reference is: S. Shafer, Using color to seperate reflection components, COLOR Res. Appl...

    Looking for resources about color-based region growing in images

    Does anybody know of any good resources for color-based region growing in images?

    What is Anti Aliasing Fliter?

    Anti-aliasing filters are generally used so that when an analog signal is sampled, the effects of aliasing don't appear in the samples. When you sample a signal at a sampling rate fs, you're limited to representing frequencies up to fs/2. If there are frequencies above fs/2 in the signal, they...

    Help me find the proof for a Fourier Transform equation

    Re: Fourier Transform In the formal definition of the Fourier Transform, there is a rule as to when the integration is valid, and it has to do with L1- and L2-integrable functions. The same applies for the inverse Fourier Transform. Things like the unit step, the signum function, and the...

    How to find a square root of a large number?

    Re: square root??? Here's an idea of how you can zone in to the value fairly quickly. For your example: Start out with 7^2=49 and 8^2 = 64. Then 70^2 = 4900 and 80^2 = 6400. So your square root is between those two numbers (70 and 80). Start by splitting the difference. 75^2 =...

    Help me find a solution to a statistics question

    This is probably way too specialized of a question to ask and expect an answer on, but I'm using "The Elements of Statistical Learning" by Hastie, Tibshirani, and Friedman, and have been working on one question for about 4 days now and still can't get it, so if anyone out there has the text and...

    Help me prove two statements for Introduction to Hilbert Spaces course

    Re: Proof Question As far as 1) goes, I just wasn't sure if there was some theorem that concretely states that if the mean of the function is 0 and it's non-negative that it has to be equal to 0. As far as 2) goes, it's easy to see that each Fn(x)->0 as |x|->inf by the definition, but I don't...

    Help me prove two statements for Introduction to Hilbert Spaces course

    Haven't taken Calculus in awhile, and have to prove two statements for my Introduction to Hilbert Spaces course. I was hoping someone may be able to enlighten me. Essentially, I have worked these two problems down to the point where I have to prove the following: 1) g(x) non-negative on [0...

    biginer in communication

    A basic understanding of LTI systems probably wouldn't hurt, either, depending on what type of systems you're studying. Specifically, knowing the basics of elementary ideal LPFs are useful when you're learning about modulation systems.
