What is Fast Fourier Transform in image processing?
The Fast Fourier Transform (FFT) is commonly used to transform an image between the spatial and frequency domain.
Unlike other domains such as Hough and Radon, the FFT method preserves all original data.
Plus, FFT fully transforms images into the frequency domain, unlike time-frequency or wavelet transforms.
Does JPEG compression use Fourier transform?
The key to the JPEG baseline compression process is a mathematical transformation known as the Discrete Cosine Transform (DCT).
The DCT is in a class of mathematical operations that includes the well known Fast Fourier Transform (FFT), as well as many others.
What is the FFT for video compression?
FFT is 1.846:1 means FFT technique can compress the video file 1.846 times of original file size.
So, the experimental result pointed that DCT has best compression rate.
Therefore, the compressed size of DCT on each video files are high light as red color.
Two image compression methods are compared: Singular Value Decomposition (SVD) and Fast Fourier Transform (FFT).
SVD is the factorization of a real or complex matrix, while FFT is an algorithm which allows low pass and high pass filtering with a great degree of accuracy.

The proposed system uses fast fourier transform (FFT) [15] with optimized threshold values for each colour channel to compress the image that the decompressed image obtains high structural similarity (SSIM) index, thus extracting the contributing characteristics of the image.
