    Hi
    I have this homeworks problem I don't know how to solve them , would you help me please ??
    Problems:
    3.1. Show that in the XYZ model the white is represented by the triple (1,1,1).
    3.2. Consider the YIQ model. Show that in a grayscale image, where R=G=B,
    the chrominance components I and Q are null.
    3.3. Consider the HSV model. Show that in the simplest form of HSV transformation,
    the hue (H) become undefined when the saturation S is null.
    3.4. Compute in HSV model, the coordinates of cyan, magenta and yellow.
    3.5. Repeat Problem 3.4 for the HSB model.

    That doesn't count as SHOWING your work. We need to see what you have done and where you are going right and where you are going wrong in order to best help you. We are NOT just going to solve it for you and give you the solutions -- that won't help you learn the subject.

    This one might also be helpful

    http://en.wikipedia.org/wiki/HSL_and_HSV

    Hint: In arithmetic the big undefined operation is division by zero. Can you find a reference to division by 0 in the article?

    Ok.
    problem 3.3
    I use this equations
    [​IMG]
    I assume that S=0 and put it in the equation, but i cant find the relation between S and H.
    Note: I am just start study image processing.

    So, how have you tried to use those equations to answer the question?

    What does it mean for H to be "undefined"? What is required for that to happen?
