The Discrete Cosine Transform, or DCT, is used throughout the MPEG standards as a way to provide video compression. This mathematical tool allows images to be represented with amazing visual accuracy ...

This important transform (DCT for short) has originated by [Ahmed et al. 74] and has been used and studied extensively since. Because of its importance for data compression, the DCT is treated here in ...

[Ottverse] has an interesting series in progress to demystify video compression. The latest installment promises to explain discrete cosine transforms as though you were five years old. We’ll be ...

Discrete transform techniques form the mathematical foundation of modern image and video compression by converting spatial or temporal pixel data into spectral coefficients that reveal salient ...
