The key contribution is that our method first proposes a grouping strategy to extract the geometric and topological features of the sequence in animation quadrangulation. Animation sequence is firstly divided into groups through picked key frames. Then analyze the local deformation of each group and detect the surface feature for each reference frame, inducing a set of hard and soft constraints for each key frame of every subgroup, next smooth the cross field of each reference frame and combine them through singularities for the whole sequence, finally compute a field guided global parametrization and quad meshes extraction with an off-the-shelf method. It is effective and easy to implement, and experiment results and comparisons show that our method achieves better quality. <\/jats:p>","DOI":"10.1142\/s0218001417540210","type":"journal-article","created":{"date-parts":[[2017,4,5]],"date-time":"2017-04-05T06:54:32Z","timestamp":1491375272000},"page":"1754021","source":"Crossref","is-referenced-by-count":0,"title":["Quadrangulations of Animation Sequence"],"prefix":"10.1142","volume":"31","author":[{"given":"Ping","family":"Du","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Shandong University, No. 1500 Shunhua Road, Jinan 250101, P.
