Generation of subsurface scattering texture maps for 3D objects

A method, comprising:

• in an electronic apparatus:
• controlling a set of light sources to generate a set of lighting patterns;
• controlling a set of image capture devices to capture a set of images of an object that is illuminated by the generated set of lighting patterns;
• determining pixel-level offset information based on application of an image registration operation on the set of images;
• generating a set of corrected images based on the pixel-level offset information and the set of images;
• and
• estimating subsurface scattering (SSS) parameters in a form of texture maps corresponding to a 3D mesh of the object,
• wherein the estimation is performed based on a fitting of a scattering model on the set of corrected images.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by an electronic apparatus, cause the electronic apparatus to execute operations, the operations comprising:

• controlling a set of light sources to generate a set of lighting patterns;
• controlling a set of image capture devices to capture a set of images of an object that is illuminated by the generated set of lighting patterns;
• determining pixel-level offset information based on application of an image registration operation on the set of images;
• generating a set of corrected images based on the pixel-level offset information and the set of images;
• and
• estimating subsurface scattering (SSS) parameters in a form of texture maps corresponding to a 3D mesh of the object,
• wherein the estimation is performed based on a fitting of a scattering model on the set of corrected images.
