[...] la norme de référence JPEG décompose tout d’abord l'image en petits blocs de 8x8 pixels et définit, pour chacun de ces blocs, la fréquence d’apparition d’un même pixel grâce à une transformée en cosinus directe(DCT pour les anglo-saxons) dérivée de la transformation de Fourier. [...] Une deuxième étape quantifie les coefficients de Fourier et opère une dégradation de l'image selon un algorithme propriétaire(non diffusé). Cette dégradation dépend du facteur de compression retenu par l'utilisateur. On admet que, pour un taux de compression compris entre 10 et 20, l'œil ne perçoit pratiquement aucun changement. Au-delà, les différences sont beaucoup plus apparentes. 1, record 2, French, - facteur%20de%20compression

Classification multispectrale. La méthode du maximum de vraisemblance a été utilisée pour classer les sols nus selon trois nouveaux groupes d’états de surface :(1) état de surface non dégradé,(2) état de surface à dégradation intermédiaire et(3) état de surface dégradé. L'information radiométrique extraite des parcelles de référence permet de décrire statistiquement les caractéristiques spectrales de chaque classe au moyen de son vecteur moyen et de la matrice de covariance. L'algorithme du maximum de vraisemblance calcule alors pour chaque pixel sa probabilité d’appartenance à chaque classe et lui attribue la classe de plus forte probabilité. 2, record 5, French, - classification%20multispectrale
