      A unique space oriented filer is presented in order to detect and isolate the cell of a nucleus for applications in cytopathology. A classification method for nuclei is then considered based on the application of a set of ...
    • Patterns of Creativity in Design 

      Bilotta, E.; Pantano, P. (The Eurographics Association, 2007)
      One of the most remarkable features of the human mind is its creativity. During the course of this talk we shall be presenting some examples of the creative use of scientific models such as Chua's attractors and Cellular ...
    • PC-GAU: PCA Basis of Scattered Gaussians for Shape Matching via Functional Maps 

      Colombo, Michele; Boracchi, Giacomo; Melzi, Simone (The Eurographics Association, 2022)
      Shape matching is a central problem in geometry processing applications, ranging from texture transfer to statistical shape analysis. The functional maps framework provides a compact representation of correspondences between ...
    • PED: Pedestrian Environment Designer 

      McIlveen, James; Maddock, Steve; Heywood, Peter; Richmond, Paul (The Eurographics Association, 2016)
      Pedestrian simulations have many uses, from pedestrian planning for architecture design through to games and entertainment. However, it is still challenging to efficiently author such simulations, especially for non-technical ...
    • Pen2VR: A Smart Pen Tool Interface for Wire Art Design in VR
