Unifying Approaches and Removing Unrealistic Assumptions in Shape from Shading: Mathematics Can Help
This article proposes a solution of the Lambertian Shape From Shading (SFS) problem by designing a new mathematical framework based on the notion of viscosity solutions. The power ...

Shape from Shading for Hybrid Surfaces
This paper presents a new method for recovering the shape of hybrid surfaces that have both diffuse reflection and specular reflection using shape from shading (SFS). The image ...

A Unifying and Rigorous Shape from Shading Method Adapted to Realistic Data and Applications
We propose a new method for the Lambertian Shape From Shading (SFS) problem based on the notion of Crandall-Lions viscosity solution. This method has the advantage of requiring the...

Restoration of images scanned from thick bound documents
Perspective distortion always occurs while scanning thick, bound documents. This distortion mainly causes two sources of degradation for the scanned grayscale image ? i) shade alo...

Perspective Nonrigid Shape and Motion Recovery
We present a closed form solution to the nonrigid shape and motion (NRSM) problem from point correspondences in multiple perspective uncalibrated views. Under the assumption that t...
