      Exposure correction is one of the fundamental tasks in image processing and computational photography. While various methods have been proposed, they either fail to produce visually pleasing results, or only work well for ...

    • Towards Robust Direction Invariance in Character Animation 

      Ma, Li-Ke; Yang, Zeshi; Guo, Baining; Yin, KangKang (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      In character animation, direction invariance is a desirable property. That is, a pose facing north and the same pose facing south are considered the same; a character that can walk to the north is expected to be able to ...

    • Figure Skating Simulation from Video 

      Yu, Ri; Park, Hwangpil; Lee, Jehee (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Figure skating is one of the most popular ice sports at the Winter Olympic Games. The skaters perform several skating skills to express the beauty of the art on ice. Skating involves moving on ice while wearing skate shoes ...

      Li, Kun; Liu, Jingying; Lai, Yu-Kun; Yang, Jingyu (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      In this work, we introduce multi-column graph convolutional networks (MGCNs), a deep generative model for 3D mesh surfaces that effectively learns a non-linear facial representation. We perform spectral decomposition of ...

    • Inertia-based Fast Vectorization of Line Drawings 

      Najgebauer, Patryk; Scherer, Rafal (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Image vectorisation is a fundamental method in graphic design and is one of the tools allowing to transfer artist work into computer graphics. The existing methods are based mainly on segmentation, or they analyse every ...

    • ManyLands: A Journey Across 4D Phase Space of Trajectories 

      Amirkhanov, Aleksandr; Kosiuk, Ilona; Szmolyan, Peter; Amirkhanov, Artem; Mistelbauer, Gabriel; Gröller, Eduard; Raidou, Renata Georgia (The Eurographics Association and John Wiley & Sons Ltd., 2019)
