Title (EN) METHOD AND APPARATUS FOR IMAGE CHARACTERIZATION
(FR) PROCEDE ET APPAREIL POUR UNE CARACTERISATION D'IMAGE
Abstract:
(EN) Method of characterizing an image comprising: defining one or more image areas of the image; analyzing color and/or intensity transitions within the image area of a predefined color basis; creating a density profile of said transitions in said image area; and fitting said density profile to a predefined parametrization function According to the method said density profile is characteristic for an image and can be used for image characterization purposes.
(FR) Procédé de caractérisation d'une image comprenant: la définition d'une ou plusieurs zones d'image de l'image; l'analyse des transitions de couleur et/ou d'intensité dans la zone d'image d'une base colorée prédéfinie; la création d'un profil de densité desdites transitions dans ladite zone d'image; et l'adaptation dudit profil de densité à une fonction de paramétrage prédéfini. Selon le procédé, ledit profil de densité est caractéristique d'une image et peut être utilisé pour des besoins de caractérisation d'image.
