Skin reflectance image correction in biometric image capture

In examples, a relative skin reflectance of a captured image of a subject is quantified. Based on the relative skin reflectance, the captured image is determined as suitable or not suitable for biometric identification. When the captured image is determined not suitable, a remedial capture setting i...

More Information
Summary:In examples, a relative skin reflectance of a captured image of a subject is quantified. Based on the relative skin reflectance, the captured image is determined as suitable or not suitable for biometric identification. When the captured image is determined not suitable, a remedial capture setting is calculated and provided to an image capturing resource. Another captured image of the subject, captured under the remedial capture setting, is received from the image capturing resource. The relative skin reflectance of the another captured image is quantified and based thereon, there is a determining of whether the another captured image is suitable or is not suitable.
