• openAccess   Particle Swarm Optimisation Based 3D Reconstruction of Sketched Line Drawings 

      Piquer, Ana; Company, Pedro; Contero, Manuel IOS Press (2004)
      The purpose of this paper is to demonstrate the application of particle swarm optimisation to line drawings reconstruction. The paper’s new contribution is the application of swarm intelligence in dealing with machine ...
    • 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 ...
