What is 2D Fourier transform used for?

BASIS FUNCTIONS:

The Fourier Transform ( in this case, the 2D Fourier Transform ) is the series expansion of an image function ( over the 2D space domain ) in terms of "cosine" image (orthonormal) basis functions.

What are the applications of FFT?

FFT Applications

These techniques can be used for a variety of signals such as audio and speech, radar, communication, and other sensor data signals. FFT is also sometimes used as an intermediate step for more complex signal processing techniques. In image processing, FFT is used for filtering and image compression.

What does 2D FFT tell you?

2D FFT (2-dimensional Fast Fourier Transform) can be used to analyze the frequency spectrum of 2D signal (matrix) data. Conversely, 2D IFFT (2-dimension Inverse Fast Fourier Transform) is able to reconstruct a 2D signal from a 2D frequency spectrum.

Where FFT is used in real life?

It is used in designing electrical circuits, solving differential equations , signal processing ,signal analysis, image processing & filtering.
