Abstract
We address the problem of integrating multi-frame stereo and
shading cues within the framework of optimization in the
infinite-dimensional space of piecewise smooth surfaces. Cue integration
then reduces to the determination of regions where prior assumptions on
the reflectance of the surfaces can be enforced. By combining cues, our
formulation allows defining a well-posed problem even when
reconstruction from stereo or shading in isolation would be ill-posed.
For a simplified model we prove the necessary conditions for optimality,
and propose an iterative optimization algorithm, which we implement
using ultra-narrowband level set methods
