Abstract[English]
Implementations generally relate to evaluation of similar content-based images. In some implementations, a method includes receiving a first image, where the first image includes at least one first object. The method further includes receiving a second image, where the second image includes at least one second object. The method further includes computing a structural similarity index measure (SSIM) value based on the at least one first object and the at least one second object. The method further includes computing a scale invariant feature transform (SIFT) value based on the at least one first object and the at least one second object. The method further includes computing a histogram value based on the at least one first object and the at least one second object. The method further includes computing a similarity score based on the SSIM value, the SIFT value, and the histogram value.[French]
Des modes de réalisation concernent de manière générale l'évaluation d'images similaires à base de contenu. Dans certains modes de réalisation, un procédé consiste à recevoir une première image, la première image comprenant au moins un premier objet. Le procédé comprend en outre la réception d'une seconde image, la seconde image comprenant au moins un second objet. Le procédé comprend en outre le calcul d'une valeur de mesure d'indice de similarité structurelle (SSIM) sur la base du ou des premiers objets et du ou des seconds objets. Le procédé comprend en outre le calcul d'une valeur de transformée de caractéristique invariante à l'échelle (SIFT) sur la base du ou des premiers objets et du ou des seconds objets. Le procédé comprend en outre le calcul d'une valeur d'histogramme basée sur le ou les premiers objets et le ou les seconds objets. Le procédé consiste en outre à calculer un score de similarité sur la base de la valeur SSIM, de la valeur SIFT et de la valeur d'histogramme.
