Method for estimating a score of adhesion between the rubber composition and the reinforcing plies of a specimen representative of a tyre to be characterized, the specimen comprising at least two reinforcing plies embedded in the rubber composition, each reinforcing ply itself comprising reinforcing cords placed beside one another, the method comprising the following stages: the specimen is baked under pressure, then a stripping test is carried out by peeling apart two reinforcing plies of the specimen, characterized in that it comprises the following stages: the two half-specimens are placed on a flatbed scanner, aligned in the scanner's image acquisition direction, an image is acquired over the entire surface of the scanner, the acquired images are cropped so as to retain only the image of the half-specimens, at least one binary segmentation mask image separating the reinforcement zones from the rubber composition zones is then determined by superpixel decomposition from the pixels of the cropped acquired images, at least one theoretical image of the reinforcing cords is generated as a function of the spacing and diameter of the reinforcing cords, a score equal to the value one minus the ratio of the surface area of the reinforcing cords in the binary segmentation mask image and the surface area of the reinforcing cords in the theoretical image of the reinforcing cords is determined. the specimen comprising at least two reinforcing plies embedded in the rubber composition, each reinforcing ply itself comprising reinforcing cords placed beside one another, the method comprising the following stages: the specimen is baked under pressure, then a stripping test is carried out by peeling apart two reinforcing plies of the specimen, characterized in that it comprises the following stages: the two half-specimens are placed on a flatbed scanner, aligned in the scanner's image acquisition direction, an image is acquired over the entire surface of the scanner, the acquired images are cropped so as to retain only the image of the half-specimens, at least one binary segmentation mask image separating the reinforcement zones from the rubber composition zones is then determined by superpixel decomposition from the pixels of the cropped acquired images, at least one theoretical image of the reinforcing cords is generated as a function of the spacing and diameter of the reinforcing cords, a score equal to the value one minus the ratio of the surface area of the reinforcing cords in the binary segmentation mask image and the surface area of the reinforcing cords in the theoretical image of the reinforcing cords is determined. the specimen is baked under pressure, then a stripping test is carried out by peeling apart two reinforcing plies of the specimen, characterized in that it comprises the following stages: the two half-specimens are placed on a flatbed scanner, aligned in the scanner's image acquisition direction, an image is acquired over the entire surface of the scanner, the acquired images are cropped so as to retain only the image of the half-specimens, at least one binary segmentation mask image separating the reinforcement zones from the rubber composition zones is then determined by superpixel decomposition from the pixels of the cropped acquired images, at least one theoretical image of the reinforcing cords is generated as a function of the spacing and diameter of the reinforcing cords, a score equal to the value one minus the ratio of the surface area of the reinforcing cords in the binary segmentation mask image and the surface area of the reinforcing cords in the theoretical image of the reinforcing cords is determined. the two half-specimens are placed on a flatbed scanner, aligned in the scanner's image acquisition direction, an image is acquired over the entire surface of the scanner, the acquired images are cropped so as to retain only the image of the half-specimens, at least one binary segmentation mask image separating the reinforcement zones from the rubber composition zones is then determined by superpixel decomposition from the pixels of the cropped acquired images, at least one theoretical image of the reinforcing cords is generated as a function of the spacing and diameter of the reinforcing cords, a score equal to the value one minus the ratio of the surface area of the reinforcing cords in the binary segmentation mask image and the surface area of the reinforcing cords in the theoretical image of the reinforcing cords is determined.
