To encode images or sounds, softwares use quantifications. For example, the standard CD encoding
uses a 44khz sampling of the volume with 16 bits. Similarly, images are represented as map of small squares called pixels, each of them having a uniform color defined by its red, green and blue components. To-
day standard encode each components with one byte, which lead to the famous 24 − bits color encoding.
This is as simple as it sounds: in the computer memory, an image is encoded as a succession of groups of three bytes, each one of those triplets corresponding to the three component red, green and blue of a point on the screen.
