Our main contribution is that we estimated the optical flow by a nonlinear filtering process instead of an energy minimizing process, the latter often needs the corresponding smoothing constraint to be restricted to some form of convex and differentiable entity. In this way, it avoids some restrictions needed by the regularization. So we can choose a nonlinear filter from more flexible forms, which can help to deal with flow discontinuities more efficiently in some sense. We modified and extended a scalar 2D bilateral filter to optical flow field as the wanted nonlinear filter. Qualitative and quantitative results show that the new method can produce a reliable result. <\/jats:p>","DOI":"10.1142\/s0219467809003368","type":"journal-article","created":{"date-parts":[[2009,2,24]],"date-time":"2009-02-24T10:35:53Z","timestamp":1235471753000},"page":"121-132","source":"Crossref","is-referenced-by-count":0,"title":["A NONLINEAR FILTERING BASED OPTICAL FLOW COMPUTATION"],"prefix":"10.1142","volume":"09","author":[{"given":"LU","family":"ZONGQING","sequence":"first","affiliation":[{"name":"The Graduate School at Shenzhen, Tsinghua University F-102, Tsinghua Campus, The University Town, Shenzhen, China, 518055, China"}]},{"given":"LIAO","family":"QINGMIN","sequence":"additional","affiliation":[{"name":"The Graduate School at Shenzhen, Tsinghua University F-102, Tsinghua Campus, The University Town, Shenzhen, China, 518055, China"}]},{"given":"PEI","family":"JIHONG","sequence":"additional","affiliation":[{"name":"Key Lab of Intelligent Information Processing, Shenzhen University, Shenzhen, China, 518060, China"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1016\/0004-3702(81)90024-2"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01420984"},{"key":"rf4","doi-asserted-by":"crossref","unstructured":"T.\u00a0Brox, Computer Vision-ECCV 2004, 3024 of Lecture Notes in Computer Science, eds.
