• openAccess   Skewed Mirror Symmetry for Depth Estimation in 3D Line-Drawings 

      Piquer, Ana; Martin, Ralph; Company, Pedro Springer (2004)
      We aim to reconstruct three-dimensional polyhedral solids from axonometric-like line sketches. A new approach is proposed to make use of planes of mirror symmetry detected in sketches. Taking into account mirror symmetry ...
    • openAccess   Skewed mirror symmetry in the 3D reconstruction of polyhedral models 

      Piquer, Ana; Company, Pedro; Martin, Ralph Center of Computer Graphics and Visualization Faculty of Applied Sciences University of West Bohemia (2003)
      We aim to reconstruct three-dimensional polyhedra from axonometric line drawings. Existence of mirror symmetry in polyhedra can assist the reconstruction process. We present a new approach for determining planes of mirror ...
