Webb22 juni 2024 · Shape from Polarization (SfP) estimates surface normals by analyzing the polarization properties of reflected light. An overview can be found in Rahmann and Canterakis ( 2001 ), which describes how the degree of polarization and orientation of specular reflections can be used to obtain surface normals.
