    • A Descriptor for Voxel Shapes Based on the Skeleton Cut Space 

      Feng, Cong; Jalba, Andrei C.; Telea, Alexandru C. (The Eurographics Association, 2016)
      Two-dimensional medial axes and three-dimensional curve skeletons have been long used for shape retrieval tasks. In contrast, and despite their ability to fully capture shape geometry and topology, three-dimensional surface ...

    • An Edit Distance for Reeb Graphs 

      Bauer, Ulrich; Fabio, Barbara Di; Landi, Claudia (The Eurographics Association, 2016)
      We consider the problem of assessing the similarity of 3D shapes using Reeb graphs from the standpoint of robustness under perturbations. For this purpose, 3D objects are viewed as spaces endowed with real-valued functions, ...

    • An Experimental Shape Matching Approach for Protein Docking 

      Fernandes, Francisco; Ferreira, Alfredo (The Eurographics Association, 2016)
      Proteins play a vital role in biological processes, with their function being largely determined by their structure. It is important to know what a protein binds, where it binds, how it binds, and what is its final ...

    • Towards an Observer-oriented Theory of Shape Comparison 

      Frosini, Patrizio (The Eurographics Association, 2016)
      In this position paper we suggest a possible metric approach to shape comparison that is based on a mathematical formalization of the concept of observer, seen as a collection of suitable operators acting on a metric space ...
