      The structure of Bulk-Heterojunction (BHJ) materials, the main component of organic photovoltaic solar cells, is very complex, and the relationship between structure and performance is still largely an open question. ...

    • Comparing Personal Image Collections with PICTuReVis 

      Corput, Paul van der; Wijk, Jarke J. van (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Digital image collections contain a wealth of information, which for instance can be used to trace illegal activities and investigate criminal networks. We present a method that enables analysts to reveal relations among ...

    • A Comprehensive Survey on Sampling‐Based Image Matting 

      Yao, Guilin; Zhao, Zhijie; Liu, Shaohui (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Sampling‐based image matting is currently playing a significant role and showing great further development potentials in image matting. However, the consequent survey articles and detailed classifications are still rare ...

    • Computational Light Painting Using a Virtual Exposure 

      Salamon, Nestor Z.; Lancelle, Marcel; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Light painting is an artform where a light source is moved during a long-exposure shot, creating trails resembling a stroke on a canvas. It is very difficult to perform because the light source needs to be moved at the ...

    • Computing Contour Trees for 2D Piecewise Polynomial Functions 

      Nucha, Girijanandan; Bonneau, Georges-Pierre; Hahmann, Stefanie; Natarajan, Vijay (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Contour trees are extensively used in scalar field analysis. The contour tree is a data structure that tracks the evolution of level set topology in a scalar field. Scalar fields are typically available as samples at ...

    • Consistent Partial Matching of Shape Collections via Sparse Modeling 

      Cosmo, L.; Rodolà, E.; Albarelli, A.; Mémoli, F.; Cremers, D. (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Recent efforts in the area of joint object matching approach the problem by taking as input a set of pairwise maps, which are then jointly optimized across the whole collection so that certain accuracy and consistency ...

    • Consistent Video Filtering for Camera Arrays 

      Bonneel, Nicolas; Tompkin, James; Sun, Deqing; Wang, Oliver; Sunkavalli, Kalyan; Paris, Sylvain; Pfister, Hanspeter (The Eurographics Association and John Wiley & Sons Ltd., 2017)
