Improved initial approximation and intensity-guided discontinuity detection in visible-surface reconstruction

Given a dense set of imperfect normals obtained by photometric stereo or shape from shading, this paper presents an optimization algorithm which alternately optimizes until convergence the surface integrabilities and discontinuities inherent in the ...

We address the problem of reconstructing a surface from sparse and noisy depth data while concurrently identifying and preserving the significant discontinuities in depth. It is well known that, starting from either the probabilistic Markov random field ...

Let $${{\mathcal {M}}} \subset \mathbb {R}^d$$ be a compact, smooth and boundaryless manifold with dimension m and unit reach. We show how to construct a function $$\varphi :\mathbb {R}^d \rightarrow \mathbb {R}^{d-m}$$ from a uniform $$(\...
