Dense Photometric Stereo Using Tensorial Belief Propagation
We address the normal reconstruction problem by photometric stereo using a uniform and dense set of photometric images captured at fixed viewpoint. Our method is robust to spurio...

Helmholtz Stereopsis: Exploiting Reciprocity for Surface Reconstruction
We present a method ? termed Helmholtz stereopsis ? for reconstructing the geometry of objects from a collection of images. Unlike existing methods for surface reconstruction (e.g...

Capturing Multiple Illumination Conditions using Time and Color Multiplexing
Many vision and graphics problems such as relighting, structured light scanning and photometric stereo, need im- ages of a scene under a number of different illumination conditi...

Mesostructure from Specularity
We describe a simple and robust method for surface mesostructure acquisition. Our method builds on the observation that specular reflection is a reliable visual cue for surface me...

Isotropy, Reciprocity and the Generalized Bas-Relief Ambiguity
A set of images of a Lambertian surface under varying lighting directions defines its shape up to a three-parameter Generalized Bas-Relief (GBR) ambiguity. In this paper, we exami...
