A Graph-Spectral Method for Surface Height Recovery
This paper describes a graph-spectral method for 3D surface integration. The algorithm takes as its input a 2D field of surface normal estimates, delivered, for instance, by a sh...

Wavelet-based Light Reconstruction from a Single Image
In this paper we propose a wavelet-based light representation. This representation is used for recovering illumination and reflectance of a scene with known geometry from a singl...
