Abstract 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.
