Theory behind Fourier Transform
The Fourier Transform (FT) is a linear transformation of f(x) to g(1/x). A common use of this is to convert an image (function of space) into a function of its spatial frequency. While this may useless at the moment, some operations and properties are easier or more obvious when done in the spatial frequency domain, instead of in the usual space domain.
This blog shall cover some basic properties and uses of the Fourier Transform.
