Shape from polarization
WebbKind Code: A1 Detailed information of a three-dimensional model necessary for photorealistic CG rendering capable of expressing the texture of the surface of an object is acquired in real time. A texture acquisition device 1 of a texture acquisition system 1000 includes a subject shape acquisition unit 120 that acquires shape information of a … Webb24 juni 2024 · Shape from Polarization for Complex Scenes in the Wild Abstract: We present a new data-driven approach with physics based priors to scene-level normal estimation from a single polarization image. Existing shape from polarization (SfP) works mainly focus on estimating the normal of a single object rather than complex scenes in …

WebbStereo data for 3D shape reconstruction. 2PW Polarimetric cues have been used in Computer Vision for a number of different tasks mostly related to the difficulty of dealing with specular highlights. In addition to using polarised image formation to separate diffuse from specu-larreflection(Nayaretal. 1993;Umeyama andGodin2004; Webb4 juli 2024 · Polarization is useful for estimating surface normals. In this paper, polarization is applied to shape estimation. Surface normal estimation from a single image is commonly performed by shape-from-shading. An alternative approach is shape-from-polarization, which usually cannot uniquely determine the surface normal and must be …
WebbA learning- based approach that learns to estimate surface normals even at low event-rates is proposed, improving the physics-based approach by 52% on the real world dataset. State-of-the-art solutions for Shape-from-Polarization (SfP) suffer from a speed-resolution tradeoff: they either sacrifice the number of polarization angles measured or necessitate … WebbarXiv.org e-Print archive
