Title (EN) METHOD FOR DISCRIMINATING TEXTURES REGIONS AND HOMOGENEOUS OR FLAT REGIONS IN AN IMAGE AND METHODS FOR ESTIMATING NOISE IN AN IMAGE SEQUENCE
(FR) PROCÉDÉ POUR DISTINGUER DES ZONES DE TEXTURE ET DES ZONES HOMOGÈNES OU PLANES DANS UNE IMAGE ET PROCÉDÉS D'ESTIMATION DE BRUIT DANS UNE SÉQUENCE D'IMAGES
Abstract: front page image
(EN)The present invention relates to a method for discriminating textured regions (TR) and homogeneous or flat regions (HR) in an image (I). According to the present invention a multi-scale or multi-resolution measurement is performed with respect to said image (I). Alternatively or additionally, said image (I) is analyzed by using a prior measured noise value and a local variance value in or with respect to said image (I).
(FR)La présente invention concerne un procédé permettant de distinguer des zones texturées (TR) et des zones homogènes et planes (HR) dans une image (I). Selon la présente invention, une mesure multi-échelle ou multi-résolution est mise en oeuvre relativement à ladite image (I). Selon une variante ou en sus, ladite image (I) est analysée au moyen d'une valeur de bruit mesurée au préalable et d'une valeur de variance locale dans ou relativement à ladite image (I).
