Claim One:
1. A method for generating a real-time realistic-looking image of a pair of virtual glasses defined as a 3D object comprising two arms, and positioned on a real user face image issued from an image, which is one of a single image, a bundle of pictures, a video clip or real-time camera streams, comprising the steps of: estimating facial parameters comprising a 3D rotation matrix, a 3D translation vector and morphology parameters, of a user's face by a face analysis element; estimating glasses positioning parameters comprising a 3D rotation matrix, a 3D translation vector, global and local deformation parameters of the virtual glasses, and arms articulation, adapted to the morphology parameters, by glasses positioning element associated with a try-on mode for look or real-size simulation; mixing the real user face image with the virtual glasses positioned in accordance with the glasses positioning parameters by a realistic rendering element; applying an opacity correction formula to translucent parts of the glasses; and wherein global and local deformation parameters of the virtual glasses comprise non-rigid deformation of arms of the virtual glasses.
