Studysummary This study presented a new algorithm and camera-based system that successfully reconstruct high-quality, 3D representations of facial hair and underlying skin surfaces even in dense regions like eyebrows. Our plain-language summary of this paper — not a Tressless recommendation.
The research developed an algorithm for simultaneous 3D reconstruction of facial hair and skin using a passive, camera-based system that captured data in a single exposure and was robust against arbitrary motion. The algorithm traced and reconstructed hairs in 3D using a multiview stereo approach, while a coupled skin-reconstruction algorithm provided the underlying skin surface, even in occluded areas. In dense hair regions, a hair-synthesis method created plausible hair fibers. The system was successfully demonstrated on several individuals, reconstructing various facial-hair styles along with the underlying skin surface.
