Detection of skin reflectance in biometric image capture

A system for quantification of phenotypes in received captured images capture for biometric matching, comprising:

• a processing system having a hardware processor configured to perform a predefined set of basic operations in response to receiving a corresponding basic instruction selected from a predefined native instruction set of codes;
• a memory, accessible to the processing system;
• and
• logic, comprising a set of machine codes stored in the memory and selected from the predefined native instruction set of codes of the hardware processor, the set of machine codes causing the hardware processor to:
• receive an image, and store the image as a received image, the received image including facial pixels and including background pixels, the facial pixels being of a face of a subject, and the facial pixels including a plurality of facial skin pixels;
• determine a relative reflectance value, indicative of a relative reflectance of at least a portion of the facial skin pixels;
• and
• generate a reflectance qualification indicator, indicating whether the relative reflectance value meets a reflectance qualification.
