A challenging problem is to provide simple yet effective control over captured and simulated crowds to synthesize intended group motions. We present a new method that blends existing crowd data to generate a new crowd animation. The new animation can include an arbitrary number of agents, extends for an arbitrary duration, and yields a natural-looking mixture of the input crowd data. The main benefit of this approach is to create new spatio-temporal crowd behavior in an intuitive and predictable manner. It is accomplished by introducing a morphable crowd model that allows us to encode the formations and individual trajectories in crowd data. Then, its original spatio-temporal behavior can be reconstructed and interpolated at an arbitrary scale using our morphable model.<\/jats:p>","DOI":"10.1145\/1882261.1866162","type":"journal-article","created":{"date-parts":[[2010,12,1]],"date-time":"2010-12-01T20:18:10Z","timestamp":1291234690000},"page":"1-10","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":76,"title":["Morphable crowds"],"prefix":"10.1145","volume":"29","author":[{"given":"Eunjung","family":"Ju","sequence":"first","affiliation":[{"name":"Seoul National University"}]},{"given":"Myung Geol","family":"Choi","sequence":"additional","affiliation":[{"name":"Seoul National University"}]},{"given":"Minji","family":"Park","sequence":"additional","affiliation":[{"name":"Seoul National University"}]},{"given":"Jehee","family":"Lee","sequence":"additional","affiliation":[{"name":"Seoul National University"}]},{"given":"Kang Hoon","family":"Lee","sequence":"additional","affiliation":[{"name":"Kwangwoon University"}]},{"given":"Shigeo","family":"Takahashi","sequence":"additional","affiliation":[{"name":"The University of Tokyo"}]}],"member":"320","published-online":{"date-parts":[[2010,12,15]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-88688-4_1"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/CVPR.2008.4587583"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/cav.v18:4\/5"},{"key":"e_1_2_2_4_1","volume-title":"Algorithmic Graph Theory","author":"Gibbons A."},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/1599470.1599494"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1145\/1028523.1028526"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/1531326.1531385"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/1015706.1015760"},{"key":"e_1_2_2_9_1","doi-asserted-by":"publisher","DOI":"10.1145\/1360612.1360679"},{"key":"e_1_2_2_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/1073368.1073409"},{"key":"e_1_2_2_11_1","doi-asserted-by":"publisher","DOI":"10.1145\/566654.566607"}],"container-title":["ACM Transactions on Graphics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/1882261.1866162","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/dl.acm.org\/doi\/pdf\/10.1145\/1882261.1866162","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,18]],"date-time":"2025-06-18T10:52:17Z","timestamp":1750243937000},"score":1,"resource":{"primary":{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/1882261.1866162"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,12]]},"references-count":11,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2010,12]]}},"alternative-id":["10.1145\/1882261.1866162"],"URL":"https:\/\/doi.org\/10.1145\/1882261.1866162","relation":{},"ISSN":["0730-0301","1557-7368"],"issn-type":[{"value":"0730-0301","type":"print"},{"value":"1557-7368","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,12]]},"assertion":[{"value":"2010-12-15","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
