Fourier maths behind an image

  1. Apr 22, 2015 #1
    I am beginer in image processing.
    Any signal whether it is 1D,2D or
    any multidimensional signal can be represented using combination of number of sine and cosine
    waves.Similerly any image can be
    termed as a sinusoidal function.
    Fourier series and transform plays
    vital role in image processing. So I
    want to know the Fourier math
    behind any Image which can
    help to understand wave
    components used in forming an
    image for example basis or
    functions etc.
    Also,are there any matlab/
    OpenCV code or results to
    understand easily these
    components(sine and cosine
    functions) present in image ?

    Have you searched for any books or articles on fourier transformations or fourier math as it is used in image processing?

    I think it's more that you're asking a very specific question which may not be easily answerable. And the formatting of your first post is bad and makes it difficult to read. Please don't make a new line of text when you're still in the middle of a sentence.
