Reflectance Transformation Imaging
Reflectance Transformation Imaging (RTI) is a powerful set of techniques (the first of which known as Polynomial Texture Maps,
PTMs) that enables us to capture photographs of objects under a several lighting conditions. Combined, these RTI images form
a single photograph in which users can relight these objects by moving the light sources around the hemisphere in front of
the object, but also specify user-defined parameters, including removing colour, making the objects more specular or diffuse
in order to investigate the surface details in depth. It can be used for forensic investigation of crime scenes as well as
cultural heritage documentation and investigation. The purpose of this project is to implement RTI methods of their preference.
