Separating the Reflection Components with the Use of Polarization
and Determining the Reflection Parameters
Toru Takahashi Yoichi Sato Katsushi Ikeuchi
We propose a new method for reproducing the reflection properties of the objects. First, we separate the reflection components by taking the images of a dielectric object through polarization filter under linearly polarized illumination. Second, for each separated reflection component, we determine the parameters of a reflection model (Torrance-Sparrow). In estimating the parameters, we use 3D mesh-model which is made from range images taken by a range sensor. Last, we synthesize the virtual image using the obtained reflection parameters.
