Abstract: The present disclosure relates to a method for expanding an image database for evaluation of eyewear compatibility. In particular, the present disclosure relates to a method, comprising receiving a user image, receiving a frame image, processing the received frame image by setting, as transparent, pixels of the received frame image except for an anterior face of the frame, defining, within the processed frame image, a left boundary and a right boundary of the anterior face of the frame, the left boundary and the right boundary corresponding to the left eye and the right eye, respectively, receiving a filter image, processing the received filter image by setting, as transparent, pixels in the received filter image outside the frame based on the left boundary and the right boundary, merging the processed frame image and the processed filter image, and overlaying the merged image onto the received user image.

Abstract: A method for determining at least one optical conception parameter for a progressive ophthalmic lens intended to equip a frame of a wearer, depending on the visual behavior of the latter. The method comprises the following steps: a) collecting a plurality of behavioral measurements relating to a plurality of gaze directions and/or positions of the wearer during a visual task; b) statistically processing said plurality of behavioral measurements in order to determine a zone of use of the area of an eyeglass fitted in said frame, said zone of use being representative of a statistical spatial distribution of said plurality of behavioral measurements; and c) determining at least one optical conception parameter for said progressive ophthalmic lens depending on a spatial extent and/or position of the zone of use.

Abstract: A method for determining a value of at least one geometrico-morphological parameter of a subject wearing an eyewear. The method including obtaining at least one image of a head of the subject wearing the eyewear, identifying simultaneously, on the at least one image obtained, a set of remarkable points of the image of the eyewear and a set of remarkable points of the image of the head of the subject, using an image processing algorithm determined based on a predetermined database comprising a plurality of reference images of heads wearing an eyewear, the image processing algorithm being based on machine learning, and determining at least one value of a geometrico-morphological parameter taking into account the sets of remarkable points of the image of the eyewear and head of the subject identified.

Abstract: A method for implemented by computer means for determining an oriented 3D representation of the head of a person in a natural visual posture, including receiving a first dataset corresponding to a first 3D representation of the head of the person in a first frame and the position of the rotation center of at least one eye of the person in said first frame, determining a second dataset corresponding to the orientation of the head of the person in a natural visual posture in a second frame, and determining an oriented 3D representation of the head of the person by orienting the first 3D representation of the head of the person based on the orientation of the head of the person in a common frame.

Abstract: Disclosed is a method for determining an updated visual correction need for designing a new vision correcting device of an individual already having a previous vision correcting device previously designed to correct his/her vision, wherein, in a first step, a previous level of correction of the previous vision correcting device is acquired, in a second step, a current vision acuity parameter of the individual wearing the previous vision correcting device is assessed, and, in a third step, the updated visual correction need is determined based on the previous level of correction of the previous vision correcting device acquired in the first step and on the current vision acuity parameter assessed in the second step. A complementary visual correction need can also be determined.
