The Fast Fourier Transform (FFT) is an implementation of the Discrete Fourier Transform (DFT) using a divide-and-conquer approach. A DFT can transform any discrete signal, such as an image, to and ...
The discrete cosine transform (DCT) remains a cornerstone of modern image and video compression techniques, enabling the decomposition of visual data into frequency components that can be efficiently ...
Image and video coding encompasses a diverse array of techniques aimed at reducing the volume of visual data for storage and transmission, while preserving perceptual quality. These methods range from ...
