The factorization allows a user to easily relight the scene, recover a portion of the scene geometry (normals), and to perform advanced image editing operations. Our method is easy to implement, robust, and provides a compact representation with good reconstruction characteristics. We show results using several publicly available time-lapse sequences.\n          <\/jats:p>","DOI":"10.1145\/1276377.1276504","type":"journal-article","created":{"date-parts":[[2007,9,14]],"date-time":"2007-09-14T13:44:55Z","timestamp":1189777495000},"page":"101","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":50,"title":["Factored time-lapse video"],"prefix":"10.1145","volume":"26","author":[{"given":"Kalyan","family":"Sunkavalli","sequence":"first","affiliation":[{"name":"MERL"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wojciech","family":"Matusik","sequence":"additional","affiliation":[{"name":"MERL"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanspeter","family":"Pfister","sequence":"additional","affiliation":[{"name":"MERL"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Szymon","family":"Rusinkiewicz","sequence":"additional","affiliation":[{"name":"Princeton University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2007,7,29]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1073204.1073268"},{"key":"e_1_2_2_2_1","unstructured":"Barrow H. and Tenenbaum J. 1978.
