Abstract

L'invention concerne un appareil de traitement de données pour compresser des données d'image comprenant au moins deux circuits configurés pour la génération d'une transformation sinusoïdale discrète quantifiée des données d'une image, et un codeur configuré pour le codage entropique de la transformation sinusoïdale discrète quantifiée des données d'une image générée par l'un desdits deux circuits.
