METHOD FOR DETERMINING A VALUE OF AT LEAST ONE GEOMETRIC PARAMETER OF A SUBJECT WEARING AN EYE WEARING

The present invention relates to a method for determining a value of at least one geometric parameter of a subject wearing an eyewear, said at least one geometric parameter comprising:-parameters relating to both the subject's head and said eyewear; or-a parameter related only to the morphology of the subject; or-only a parameter relating to the geometry of the eye wear; the method is computer-implemented in which the following steps are performed: a) obtaining at least one image of the head of a subject wearing the eyewear; b) simultaneously identifying, on said at least one image obtained in step a), a set of salient points of the image of the eyewear (I10) and a set of salient points of the image of the subject's head (I20) using an image processing algorithm determined on the basis of a predetermined database comprising a plurality of reference images of the head wearing the eyewear, the image processing algorithm is based on machine learning, c) determining the at least one value of the geometric morphol
