1. A computer-implemented method comprising: determining, from an image of the person, points that define a boundary around the person's face; selecting two or more different points that define the boundary of the cheeks on one side of the face, and two or more different points that define the boundary of the chin on one side of the face; determining a single deformation factor (w i — cheek ) for all the selected points that define the boundary of the cheeks on one side of the face using a first equation; determining a single deformation factor (w i — chin ) for all the selected points that define the boundary of the chin on one side of the face using a second equation, where the second equation is different from the first equation; determining, for each of the selected points, a respective non-zero deformation vector) ({right arrow over (v)} d — cheek , {right arrow over (v)} d — chin ) based at least on a weight value factor (A) that specifies the extent to which the face is to be thinned or fattened, on the respective deformation factor (w i — cheek , w i — chin ) for the selected point, and on a scale factor (s) that influences the respective deformation vector ({right arrow over (v)} d — cheek , {right arrow over (v)} d — chin ) based on a size of the person's head and that is calculated by dividing a width of the face by an adjustable parameter (B); applying the respective deformation vector ({right arrow over (v)} d — cheek , {right arrow over (v)} d — chin ) to each selected point to generate a face mesh of relocated points; and generating a reshaped image of the person's face using the face mesh.
