Title (EN) ROTATION-INVARIANT TEXTURE IMAGE DESCRIPTORS
(FR) DESCRIPTEURS D'IMAGE À TEXTURE INVARIANTE EN ROTATION
Abstract:
(EN) A method of evolving an image descriptor comprises receiving a set of pixel values associated to an image or part thereof; applying at least two first-order statistical functions to the set of pixel values to obtain respective function outputs; and applying at least one arithmetic operator to a pair of function outputs to obtain at least one arithmetic output.
(FR) Un procédé d'évolution d'un descripteur d'image consiste à recevoir un ensemble de valeurs de pixel associées à une image ou à une partie de celle-ci ; à appliquer au moins deux fonctions statistiques de premier ordre à l'ensemble de valeurs de pixel pour obtenir des sorties de fonction respectives ; et à appliquer au moins un opérateur arithmétique à une paire de sorties de fonction pour obtenir au moins une sortie arithmétique.
