Although facial hair plays an important role in individual expression, facial-hair reconstruction is not addressed by current face-capture systems.
Our research addresses this limitation with an algorithm that treats hair and skin surface capture together in a coupled fashion so that a high-quality representation of hair ﬁbers as well as the underlying skin surface can be reconstructed.
We propose a passive, camera-based system that is robust against arbitrary motion since all data is acquired within the time period of a single exposure.
Our reconstruction algorithm detects and traces hairs in the captured images and reconstructs them in 3D using a multi-view stereo approach.
Our coupled skin-reconstruction algorithm uses information about the detected hairs to deliver a skin surface that lies underneath all hairs irrespective of occlusions.
In dense regions like eyebrows, we employ a hair-synthesis method to create hair ﬁbers that plausibly match the image data.
We demonstrate our scanning system on a number of individuals and show that it can successfully reconstruct a variety of facial-hair styles together with the underlying skin surface.
