  1. 计算机科学国家重点实验室 迎新报告会 舒悦 Chinese Academy of Sciences 图形组 陈彦云 Chinese Academy of Sciences

  2. OBJECTIVE Input an image of an aggregate material Generate a solid texture with similar appearance 2014迎新报告会 —— 舒悦

  3. WHY? Cobbled Road Volcanic Stone Aggregate Material Terrazzo Spotted Animal 2014迎新报告会 —— 舒悦

  4. Solid Texture Synthesis PRIOR WORK Procedural texture • Simple & Fast • Need parameters • Fail to maintain interior structure Perlin Noise [Perlin, 1985] Cellular Texture [Worley, 1996] [Lagae et al., 2009] Perlin ‘85 Worley ‘96 Lagae et al. ‘09 2014迎新报告会 —— 舒悦

  5. Wide range of applications • High computation and memory assumption • Pixel-based • Structure and color mixture Example-based Synthesis Solid Texture Synthesis PRIOR WORK [Kopf et al., 2007] [Dong et al., 2008] [Du et al., 2013] Du et al. ‘13 Dong et al. ‘08 Kopf et al. ‘07 2014迎新报告会 —— 舒悦

  6. Solid Texture Synthesis PRIOR WORK • Plausible appearance • Clear structure • Construct particle manually • Pixel-based Stereology [Jagnow et al., 2004] Jagnow et al. ‘04 • Vector • Low storage • Need 3D exampler • Structure mixture Vector [Wang et al., 2010] Wang et al. 2010 2014迎新报告会 —— 舒悦

  7. OUR WORK Stereology + Cellular texture • Efficient rendering • Low memory cost • Resolution independent • Synthesize from image directly • Recover structure and color well 2014迎新报告会 —— 舒悦

  8. 心得体会 • 实验室的一天: • 早上到实验室 -> 放松一下,劳逸结合 -> 朋友圈,微博,知乎,什么值得买…该吃午饭了… • 下午到实验室 -> 放松一下,劳逸结合-> 朋友圈,微博,知乎,什么值得买…该吃晚饭了… • 晚上到实验室 -> 放松一下,劳逸结合 -> 朋友圈,微博,知乎,什么值得买…12点了,神马都木有干… • 太内疚了,要不要熬夜干下活… 拖延症晚期

  9. 心得体会 科研前 科研后

  10. 心得体会

  11. 血泪教训 出国: 研一搞定英语;研二出好文章 找工作:研一好好科研,出文章; 研二专注科研

  12. 再 见 !
