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.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
I'm interested to know whether the equation $$1 = 2 - \frac{1}{2 - \frac{1}{2 - \cdots}}$$ is true or not. It can be shown easily that if the continued fraction converges, it cannot converge to anything else than 1. It seems that if the continued fraction converges, the convergence is very slow. The apparent slowness of the convergence makes it difficult to estimate the presence of true convergence numerically. At the moment I don't know whether this converges or not.
