While previous edge snapping methods aim at optimizing individual strokes, we show that a co-analysis of multiple roughly placed nearby strokes better captures the user's intent. We formulate automatic sketch improvement as a three-level optimization problem and present an efficient solution to it. EZ-Sketching can tolerate errors from various sources such as indirect control and inherently inaccurate input, and works well for sketching on touch devices with small screens using fingers. Our user study confirms that the drawings our approach helped generate show closer resemblance to the traced images, and are often aesthetically more pleasing.\n          <\/jats:p>","DOI":"10.1145\/2601097.2601202","type":"journal-article","created":{"date-parts":[[2014,7,22]],"date-time":"2014-07-22T15:08:20Z","timestamp":1406041700000},"page":"1-9","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":28,"title":["EZ-sketching"],"prefix":"10.1145","volume":"33","author":[{"given":"Qingkun","family":"Su","sequence":"first","affiliation":[{"name":"Hong Kong University of Science and Technology"}]},{"given":"Wing Ho Andy","family":"Li","sequence":"additional","affiliation":[{"name":"City University of Hong Kong"}]},{"given":"Jue","family":"Wang","sequence":"additional","affiliation":[{"name":"Adobe Research"}]},{"given":"Hongbo","family":"Fu","sequence":"additional","affiliation":[{"name":"City University of Hong Kong"}]}],"member":"320","published-online":{"date-parts":[[2014,7,27]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/TPAMI.2010.161"},{"key":"e_1_2_2_2_1","volume-title":"ICIP","author":"Bao B.","year":"2012","unstructured":"Bao , B. , and Fu , H . 2012.
