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 multiview 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.<\/jats:p>","DOI":"10.1145\/2185520.2185613","type":"journal-article","created":{"date-parts":[[2012,8,6]],"date-time":"2012-08-06T18:11:37Z","timestamp":1344276697000},"page":"1-10","update-policy":"https:\/\/linproxy.fan.workers.dev:443\/https\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":68,"title":["Coupled 3D reconstruction of sparse facial hair and skin"],"prefix":"10.1145","volume":"31","author":[{"given":"Thabo","family":"Beeler","sequence":"first","affiliation":[{"name":"Disney Research Zurich and ETH Zurich"}]},{"given":"Bernd","family":"Bickel","sequence":"additional","affiliation":[{"name":"Disney Research Zurich"}]},{"given":"Gioacchino","family":"Noris","sequence":"additional","affiliation":[{"name":"Disney Research Zurich and ETH Zurich"}]},{"given":"Paul","family":"Beardsley","sequence":"additional","affiliation":[{"name":"Disney Research Zurich"}]},{"given":"Steve","family":"Marschner","sequence":"additional","affiliation":[{"name":"Disney Research Zurich and Cornell University"}]},{"given":"Robert W.","family":"Sumner","sequence":"additional","affiliation":[{"name":"Disney Research Zurich"}]},{"given":"Markus","family":"Gross","sequence":"additional","affiliation":[{"name":"Disney Research Zurich and ETH Zurich"}]}],"member":"320","published-online":{"date-parts":[[2012,7]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1667239.1667251"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/1778765.1778777"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/2010324.1964970"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/311535.311556"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/1778765.1778778"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/TPAMI.1986.4767851"},{"key":"e_1_2_2_7_1","unstructured":"Dal\u00ed S. and Halsman P. 1954.
