Robust photometric stereo using sparse regression

In this paper we propose a novel solution to uncalibrated photometric stereo. Our approach is to eliminate the so-called generalized bas relief (GBR) ambiguity by exploiting points where the Lambertian reflection is maximal. We demonstrate several ...

Visually coherent rendering for augmented reality is concerned with seamlessly blending the virtual world and the real world in real-time. One challenge in achieving this is the correct handling of lighting. We are interested in applying real-world ...

This paper studies the problem of simultaneously aligning a batch of linearly correlated images despite gross corruption (such as occlusion). Our method seeks an optimal set of image domain transformations such that the matrix of transformed images can ...
