Discrete Cosine Transform (DCT) really explained in detail

The discrete cosine transform (DCT) is the basis of many compression methods that are still used in many places. Ranging from (Motion) JPEG to ProRes is found this method of local frame rate-cutting in many compression methods for motion pictures. We are in the last 20 years already encountered many DCT explanations, but this video of computerphile are particularly hard to make the background of the process really understand in a quarter of an hour. Of course you have to understand those Backgrounds compression technology not so profound to make good movies. And we are not even sure if we would understand the video if we did not previously know would how it works. Wen, however interesting, exactly what is behind an  more infos at bei www.youtube.com deutsche Version dieser Seite: Diskrete Cosinus Transformation (DCT) wirklich ausführlich erklärt
