  • Patent number: 12079854
    Abstract: A system for determining a skin tone of a user. Herein, a server arrangement obtains an input image capturing at least a face of the user; analyze the input image to identify at least one first region of the input image that corresponds to a sclera of the user; determine a representative pixel value of the sclera; determine at least one second region of the input image that corresponds to a skin of the user; normalize pixel values of pixels in the at least one second region; determine a representative pixel value of the skin from the normalized pixel values of the pixels in the at least one second region; and select, from amongst a palette of skin tones, a skin tone whose pixel value matches with the representative pixel value of the skin. Herein, the selected skin tone is determined as the skin tone of the user.

  • Patent number: 12029483
    Abstract: An eye segmentation system for determining a center point of an eye, a radius of an iris of the eye, and an area of interest from a white area (sclera) of the eye. The system includes at least one input interface that receives a facial image of a user, wherein the facial image is captured using an image capturing device and a data processing arrangement that receives the facial image of the user as input data and processes the facial image to segment an eye region of the facial image. The system determines an eye that is suitable for segmentation from a left eye and a right eye using at least one quality metric, determines a center point of the eye using at least one directional filter, determines, using the at least one directional filter, a radius of an iris of the eye from the center point of the eye.
