However, good lighting design typically requires complex equipment and significant time and expertise. Our work simplifies this task using a relighting technique that transfers the desired illumination of one portrait onto another. The novelty in our approach to this challenging problem is our formulation of relighting as a mass transport problem. We start from standard color histogram matching that only captures the overall tone of the illumination, and we show how to use the mass-transport formulation to make it dependent on facial geometry. We fit a three-dimensional (3D) morphable face model to the portrait, and for each pixel, we combine the color value with the corresponding 3D position and normal. We then solve a mass-transport problem in this augmented space to generate a color remapping that achieves localized, geometry-aware relighting. Our technique is robust to variations in facial appearance and small errors in face reconstruction. As we demonstrate, this allows our technique to handle a variety of portraits and illumination conditions, including scenarios that are challenging for previous methods.<\/jats:p>","DOI":"10.1145\/3095816","type":"journal-article","created":{"date-parts":[[2017,10,10]],"date-time":"2017-10-10T12:17:08Z","timestamp":1507637828000},"page":"1-15","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":19,"title":["Portrait Lighting Transfer Using a Mass Transport Approach"],"prefix":"10.1145","volume":"37","author":[{"given":"Zhixin","family":"Shu","sequence":"first","affiliation":[{"name":"Stony Brook University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sunil","family":"Hadap","sequence":"additional","affiliation":[{"name":"Adobe Research, San Jose, CA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eli","family":"Shechtman","sequence":"additional","affiliation":[{"name":"Adobe Research, Seattle, WA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kalyan","family":"Sunkavalli","sequence":"additional","affiliation":[{"name":"Adobe Research, San Jose, CA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sylvain","family":"Paris","sequence":"additional","affiliation":[{"name":"Adobe Research, Cambridge, MA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dimitris","family":"Samaras","sequence":"additional","affiliation":[{"name":"Stony Brook University and CentraleSup\u00e9lec, Universit\u00e9 Paris-Saclay"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2017,10,10]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/34.598229"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/1667239.1667251"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/1141911.1141935"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/1360612.1360638"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/311535.311556"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10851-014-0506-3"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/2816795.2818107"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/2070781.2024192"},{"key":"e_1_2_2_9_1","doi-asserted-by":"publisher","DOI":"10.1109\/CVPR.2011.5995473"},{"key":"e_1_2_2_10_1","volume-title":"Proceedings of NIPS. 2292--2300","author":"Cuturi Marco","year":"2013","unstructured":"Marco Cuturi . 2013 .
