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 ...

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 ...

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 ...

We’ve all been victims of bad memes on the Internet, but they’re not all just bad jokes gone wrong. Some are simply bad as a result of being copies-of-copies, as each reposter adds another layer of ...
