Shape from polarization
WebbThe polarization state of light used to image the retina, and the way in which polarization can be modified by ophthalmic instruments and by the eye can have a profound impact … Webb1 okt. 2012 · Shape from polarization consists in measuring the azimuthal and zenithal angles characterizing the normal of each point of the observed surface. We focus on the ambiguity in the measurement of the zenithal angle and propose a general multispectral approach for estimating the appropriate value of this angle.

Webb13 apr. 2024 · Existing shape from polarization(SfP) methods have the difficulty in estimating transparent shape since the inherent transmission interference heavily reduces the reliability of physics-based prior. To address this challenge, we propose the concept of physics-based prior, which is inspired by the characteristic that the transmission … Webb25 mars 2024 · We study the blending of physics and deep learning in the context of Shape from Polarization (SfP).
