The subject disclosure is directed towards reconstructing an approximate hair surface using refinement of hair strands. Hair strands are first extracted from 2D images of a camera array, and projected onto a 3D visual hull. The 3D positions of these strands are refined by optimizing an objective function that takes into account orientation consistency, a visual hull constraint and/or smoothness constraints defined at the strand, wisp and/or global levels. |
