Efficient and accurate key frames extraction methods can improve the accuracy of motion synthesis. In this paper, we use an optimized t-Stochastic Neighbor Embedding (t-SNE for short) algorithm to reduce the data and on this basis extract the key frames. The experimental results show that the validity of this method is better than the existing methods under the same experimental data.<\/jats:p>","DOI":"10.3390\/sym7020395","type":"journal-article","created":{"date-parts":[[2015,4,22]],"date-time":"2015-04-22T04:41:53Z","timestamp":1429677713000},"page":"395-411","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Motion Key-Frame Extraction by Using Optimized t-Stochastic Neighbor Embedding"],"prefix":"10.3390","volume":"7","author":[{"given":"Qiang","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory of Advanced Design and Intelligent Computing, Dalian University,  Ministry of Education, Dalian 116622, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Yao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Design and Intelligent Computing, Dalian University,  Ministry of Education, Dalian 116622, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dongsheng","family":"Zhou","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Design and Intelligent Computing, Dalian University,  Ministry of Education, Dalian 116622, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rui","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Design and Intelligent Computing, Dalian University,  Ministry of Education, Dalian 116622, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,4,21]]},"reference":[{"key":"ref_1","unstructured":"Zhao, L., and Safonova, A.
