摘要： A method is provided for tracking a face of an individual in a video stream acquired by an image-acquisition device, the face wearing a pair of spectacles. The method includes evaluating parameters of a representation of the face including a model of the pair of spectacles and a model of the face so that the representation of the face is superimposed on the image of the face in the video stream, the parameters being evaluated with respect to a plurality of characteristic points of the representation of the face, previously detected in an image of the video stream, referred to as first image, wherein all or some of the parameters of the representation are evaluated by taking account of at least one proximity constraint between at least one point of the model of the face and at least one point of the model of the pair of spectacles.

摘要： The method for encoding/decoding three-dimensional meshes of dots or vertices connected in the form of facets delimited by edges; the mesh M is defined by connectivity data T and geometry data G includes the steps of: lossless encoding of the connectivity data T into encoded connectivity data Tc, iteratively generating a progressive mesh hierarchy, i.e. a set of meshes with progressive levels of detail, PM (M*), generating a piecewise smooth approximation M* of the original mesh M, from the mesh connectivity T; this smooth approximation M* being described as follows: a. compressed connectivity data Tc; b. a small number N of control dots and c. a number of indexes S of edges called protruding edges of the mesh M, identified beforehand, using the progressive mesh hierarchy PM(M*) to calculate a prediction of approximation errors in M* compared with the original mesh M.

摘要： A method for generating a final image from an initial image including an object suitable to be worn by an individual. The presence of the object in the initial image is detected. A first layer is superposed on the initial image. The first layer includes a mask at least partially covering the object in the initial image. The appearance of at least one part of the mask is modified. The suppression of all or part of an object in an image or a video is enabled. Also, a process of augmented reality intended to be used by an individual wearing a vision device on the face, and a try-on device for a virtual object.

摘要： A method for generating a final image of an individual from an initial image of the individual acquired by a camera, the image being a still or contained in a video stream. The method includes detecting the face of the individual in the initial image, realistic positioning of a virtual frame on the face of the individual, generating an overlay that is superimposed on the initial image, the overlay comprising a projection of all or a portion of the virtual frame, generating the final image by merging the overlay with the initial image. The frame includes at least one ophthalmic lens characterized by an optical correction and/or an optical treatment. The method also includes, before the final step, a step of calculating the rendering of the ophthalmic lens according to the refraction of the ophthalmic lens and of a depth map of the initial image.

摘要： Disclosed is a method for determining at least one ocular measurement (pupillary distance, mono pupillary distance and/or heights) of a user, using a consumer-type digital image sensor. The method uses at least one image of the user's head, acquired by the image sensor and containing an object of known size. The calibration parameters of the camera are unknown or known with little precision.
