Webb25 mars 2024 · We study the blending of physics and deep learning in the context of Shape from Polarization (SfP). The classic SfP problem recovers an object's shape from polarized photographs of the scene. The SfP problem is special because the physical models are only approximate. Previous attempts to solve SfP have been purely model-based, and … WebbFormula of Polarization. Polarization angle or Brewster’s angle formula is given by: tanθ = n 2 / n 1. Where, n 1 is the initial medium; n 2 is the other medium; I is the I o cos 2 θ; …
