Abstract

AbstractReconstructing 3D hair is challenging due to its complex micro‐scale geometry, and is of essential importance for the efficient creation of high‐fidelity virtual humans. Existing hair capture methods based on multi‐view stereo tend to generate results that are noisy and inaccurate. In this study, we propose a refinement method for hair geometry by incorporating the gradient of strands into the computation of their position. We formulate a gradient integration strategy for hair strands. We evaluate the performance of our method using a synthetic multi‐view dataset containing four hairstyles, and show that our refinement produces more accurate hair geometry. Furthermore, we tested our method with a real image input. Our method produces a plausible result. Our source code is publicly available at https://github.com/elerac/strand_integration.
