System and method for determining a skin tone

A system for determining a skin tone of a user, the system comprising a server arrangement communicably coupled via a data communication network to a user device associated with the user, wherein the server arrangement is configured to

• obtain 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 from pixel values of pixels in the at least one first region of the input image;
• determine at least one second region of the input image that corresponds to a skin of the user, based on at least one of:
• an analysis of the input image, an input received from the user device that is indicative of the user's selection of the at least one second region of the input image;
• normalize pixel values of pixels in the at least one second region or an entirety of the input image, based on a difference between the representative pixel value of the sclera and a reference pixel value;
• 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, wherein the selected skin tone is determined as the skin tone of the user.

• and
• selecting, from amongst a palette of skin tones, a skin tone whose pixel value matches with the representative pixel value of the skin, wherein the selected skin tone is determined as the skin tone of the user.

A computer program product for determining a skin tone of a user, the computer program product comprising a non-transitory machine-readable data storage medium having stored thereon program instructions that, when accessed by a processing device, cause the processing device to:

• obtain 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 from pixel values of pixels in the at least one first region of the input image;
• determine at least one second region of the input image that corresponds to a skin of the user, based on at least one of:
• an analysis of the input image, an input indicative of the user's selection of the at least one second region of the input image;

• 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, wherein the selected skin tone is determined as the skin tone of the user.
