In this paper, as a preceding step to the nonrigid recovery of a deforming object, we develop an approach for estimating the approximate average shape and motion of the object. This reasonably solves the ambiguity problem in nonrigid recovery. By investigating the internal structures of nonrigid objects, we introduce a novel concept, called DoN (Degree of Nonrigidity). Based on this, we propose an iterative certainty reweighted factorization method. In addition, we refine and improve the method by reformulating it in a robust manner to cope with outliers existing in the tracked features. Finally, we present some experimental results on both synthetic data and a real video sequence. <\/jats:p>","DOI":"10.1142\/s0218001405004150","type":"journal-article","created":{"date-parts":[[2005,7,6]],"date-time":"2005-07-06T22:21:56Z","timestamp":1120688516000},"page":"585-601","source":"Crossref","is-referenced-by-count":5,"title":["ESTIMATING APPROXIMATE AVERAGE SHAPE AND MOTION OF DEFORMING OBJECTS WITH A MONOCULAR VIEW"],"prefix":"10.1142","volume":"19","author":[{"given":"TAEONE","family":"KIM","sequence":"first","affiliation":[{"name":"Department of Electronic and Electrical Engineering, Pohang University of Science and Technology (POSTECH), San 31, Hyojadong, Namgu, Pohang 790-784, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KI-SANG","family":"HONG","sequence":"additional","affiliation":[{"name":"Department of Electronic and Electrical Engineering, Pohang University of Science and Technology (POSTECH), San 31, Hyojadong, Namgu, Pohang 790-784, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"p_1","doi-asserted-by":"publisher","DOI":"10.1006\/cviu.1997.0620"},{"key":"p_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0734-189X(89)80014-3"},{"key":"p_8","doi-asserted-by":"publisher","DOI":"10.1109\/42.938251"},{"key":"p_16","doi-asserted-by":"publisher","DOI":"10.1109\/34.85661"}],"container-title":["International Journal of Pattern Recognition and Artificial Intelligence"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218001405004150","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,7]],"date-time":"2019-08-07T16:42:40Z","timestamp":1565196160000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218001405004150"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2005,6]]},"references-count":4,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2011,11,21]]},"published-print":{"date-parts":[[2005,6]]}},"alternative-id":["10.1142\/S0218001405004150"],"URL":"https:\/\/doi.org\/10.1142\/s0218001405004150","relation":{},"ISSN":["0218-0014","1793-6381"],"issn-type":[{"value":"0218-0014","type":"print"},{"value":"1793-6381","type":"electronic"}],"subject":[],"published":{"date-parts":[[2005,6]]}}}
