Nous proposons une étude de l’utilisation avancée de l’hypothèse de blancheur du bruit pour améliorer les performances de débruitage. Nous mettons en avant l’intérêt d’évaluer la blancheur du résidu par des mesures de corrélation dans différents cadres applicatifs. Dans un premier temps, nous nous plaçons dans un cadre variationnel et nous montrons qu’un terme de contrainte sur la blancheur du résidu peut remplacer l’attache aux données L2 en améliorant significativement les performances de débruitage. Nous le complétons ensuite par des termes de contrôle de la distribution du résidu au moyen des moments bruts. Dans une seconde partie, nous proposons une alternative au rapport de vraisemblance menant, à la norme L2 dans le cas Gaussien blan...
