The proposed DPW allows subsignal translations without any additional costs when their starting points are matched to other points through the matching process. Because the movement of subsignals is cost-free, except for the distance between the two starting points, an adequate movement \u2014 finding and matching similar subsignals \u2014 could significantly reduce the matching cost. This feature causes a tendency to match with the least amount of subsignal movement in the result. In order to evaluate the proposed method of solving this problem, two experiments were conducted: an accuracy test for matching similar handwriting and a utility test for signature verification. For the former, we proposed the new concept of ideal matching between two handwriting signals using the affine transformation; the results of this test verified the superiority of the proposed DPW over conventional methods in reducing matching errors. Further, DPW significantly outperformed the conventional methods in the latter test. <\/jats:p>","DOI":"10.1142\/s0218001409007454","type":"journal-article","created":{"date-parts":[[2009,8,12]],"date-time":"2009-08-12T11:02:58Z","timestamp":1250074978000},"page":"967-986","source":"Crossref","is-referenced-by-count":13,"title":["DYNAMIC POSITIONAL WARPING: DYNAMIC TIME WARPING FOR ONLINE HANDWRITING"],"prefix":"10.1142","volume":"23","author":[{"given":"WON-DU","family":"CHANG","sequence":"first","affiliation":[{"name":"Graduate School of Computer Science and Engineering, The University of Aizu, Aizuwakamatsu City, Fukushima 965-8580, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JUNGPIL","family":"SHIN","sequence":"additional","affiliation":[{"name":"Graduate School of Computer Science and Engineering, The University of Aizu, Aizuwakamatsu City, Fukushima 965-8580, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1016\/j.patcog.2006.12.005"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1109\/TPAMI.2004.1262308"},{"key":"rf3","volume-title":"Discrete Mathematics","author":"Johnsonbaugh R.","year":"1997"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1016\/j.patrec.2005.09.022"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1007\/3-540-47917-1_17"},{"key":"rf8","first-page":"358","volume":"7","author":"Ratanamahatana C.
