HAIR SURFACE RECONSTRUCTION FROM WIDE-BASELINE CAMERA ARRAYS

摘要

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.

主权项

1. A method implemented at least in part on at least one processor, comprising, processing a plurality of images obtained from a wide baseline camera array into output rendering data that includes reconstructed hair data, including extracting strand data from the images, and refining the strand data including optimizing projected orientation consistency using one or more constraints.
