Shape and Refractive Index from Polarisation

摘要: In this chapter, we address the problem of simultaneous recovery shape and refractive index an object from a spectro-polarimetric image captured single view. Here, focus on diffuse polarisation process occurring at dielectric surfaces due to subsurface scattering transmission surface into air. The reflection is modelled by Fresnel theory. We present method for estimating azimuth angle normals spectral variation phase polarisation. Moreover, estimate zenith refraction simultaneously in well-posed optimisation framework. achieve well-posedness introducing two additional constraints problem, including integrability material dispersion equation. This yields iterative solution which computationally efficient use closed-form solutions both each iteration.
