Webb13 nov. 2024 · Shape from polarization (SfP) focuses on the inference of shape (normally represented as surface normal) from the polarimetric information in the multiple channels of a polarization image, captured under linear polarizers with different angles. The main issue of SfP is angle ambiguity. 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.
