      Beecham, Roger; Rooney, Chris; Meier, Sebastian; Dykes, Jason; Slingsby, Aidan; Turkay, Cagatay; Wood, Jo; Wong, B. L. William (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Many datasets have multiple perspectives - for example space, time and description - and often analysts are required to study these multiple perspectives concurrently. This concurrent analysis becomes difficult when data ...
    • Facial Cartography: Interactive Scan Correspondence 

      Wilson, Cyrus A.; Alexander, Oleg; Tunwattanapong, Borom; Ghosh, Pieter PeersAbhijeet; Busch, Jay; Hartholt, Arno; Debevec, Paul (The Eurographics Association, 2011)
      We present a semi-automatic technique for computing surface correspondences between 3D facial scans in different expressions, such that scan data can be mapped into a common domain for facial animation. The technique can ...
    • Facial Performance Capture by Embedded Photo Reflective Sensors on A Smart Eyewear 

      Asano, Nao; Masai, Katsutoshi; Sugiura, Yuta; Sugimoto, Maki (The Eurographics Association, 2017)
      Facial performance capture is used for animation production that projects a performer's facial expression to a computer graphics model. Retro-reflective markers and cameras are widely used for the performance capture. To ...
    • Factorized Point Based Global Illumination
