Title (EN) DETERMINING INTENSITY SIMILARITY IN LOW-LIGHT CONDITIONS USING THE POISSON-QUANTIZATION NOISE MODEL
(FR) DETERMINATION DE LA SIMILITUDE D’INTENSITE DANS DES CONDITIONS DE FAIBLE LUMINOSITE A L’AIDE DU MODELE DE BRUIT DE POISSON-QUANTIFICATION
Abstract: front page image
(EN)A Poisson-quantization noise model for modeling noise in low-light conditions is described. In one aspect, image information is received. A Poisson-quantization noise model is then generated from a Poisson noise model and a quantization noise model. Poisson-quantization noise is then estimated in the image information using the Poisson-quantization noise model.
(FR)La présente invention concerne un modèle de bruit de Poisson-quantification destiné à modéliser le bruit dans des conditions de faible luminosité. Dans un mode de réalisation, des données d’image sont reçues. Puis, un modèle de bruit de Poisson et un modèle de bruit de quantification génèrent un modèle de bruit de Poisson-quantification. Les données d’image permettent ensuite d’évaluer le bruit de Poisson-quantification grâce au modèle de bruit de Poisson-quantification.
