How Does Fourier Math Apply to Image Processing?

[ramdas]

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 ?

Am i asking wrong question?if yes please correct me. Also can anyone shift my question to suitable forum if I am in wrong forum.thank you.

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.
