Abstract: Digital imaging systems and methods are described for analyzing pixel data of an image of a shaving stroke for determining pressure being applied to a user's skin. A plurality of training images of a plurality of individuals are aggregated, each of the training images comprising pixel data of a respective individual when shaving with a shaving razor. A pressure model, trained with the pixel data, is operable to determine pressure being applied to the respective individual's skin. An image of a user when shaving with the shaving razor is received and analyzed, by the pressure model, to determine a user-specific pressure being applied to the user's skin by the shaving razor when a user shaving stroke is taken. A user-specific electronic recommendation to address at least one feature identifiable within the pixel data is generated and rendered, on a display screen of a user computing device.

Abstract: A cassette includes a light transmissive window through which a temporally and spatially modulated image is passed. The window has a bottom surface, as part of the cassette, or as a separate component which may be separately interchangeable in the apparatus, or a part of the apparatus. In some embodiments: (i) the window bottom surface comprises a convex surface or consists essentially of a convex surface (e.g., without additional optical structure associated therewith); (ii) the window bottom surface comprises a concave surface or consists essentially of a concave surface (e.g., without additional optical structure associated therewith); (iii) the window bottom surface has a diffraction grating or Fresnel lens thereon or operatively associated therewith; (iv) a combination of (i) and (iii); or (v) a combination of (ii) and (iii).
