Skin reflectance image correction in biometric image capture

An apparatus for quantification of phenotypes in received captured images and remediation of image capture, for biometric matching, comprising:

• a processing system having a hardware processor configured to perform a predefined set of basic operations by loading corresponding ones of a predefined native instruction set of codes, the predefined native instruction set of codes constituting a set of instructions selectable for execution by the hardware processor;
• a memory accessible to the processing system;
• a communication controller, under control of the processing system, adapted to receive an indication that a first relative skin reflectance value derived from a first image of a subject is outside of a predetermined range;
• image processing logic, stored in the memory, comprising a respective sequence of instructions selected from the predefined native instruction set of codes of the hardware processor, adapted to calculate an adjustment of one or more conditions for capture of a second image of the subject, as a remedial capture setting;
• image capture logic, stored in the memory, comprising another respective sequence of instructions selected from the predefined native instruction set of codes of the hardware processor, adapted to capture the second image of the subject under the remedial capture setting;
• the image processing logic being further adapted to:
• derive, from the second image, a second relative skin reflectance value for a face of the subject;
• a post capture reflectance correction logic configured to apply post processing to the second image to form a processed second image;
• the post processing configured to adjust the second relative reflectance value of the second image to be above a floor threshold and a below a ceiling threshold;
• the image processing logic configured to determine that the second relative reflective value of the processed second image is either below the floor threshold or above the ceiling threshold despite the adjustment made by the post capture reflectance correction logic;
• a reference images gallery configured to store a refence image of the subject;
• and
• a fallback biometric identification logic triggered to perform biometric comparison between the processed second image and a stored reference image when the second relative reflective value of the processed second image is either below the floor threshold or above the ceiling threshold.
