  • Active testing search for point cloud matching 

    Amável Pinheiro, Miguel; Sznitman, Raphael; Serradell, Eduard; Kybic, Jan; Moreno-Noguer, Francesc; Fua, Pascal (Springer, 2013)
    Conference report
    Open Access
    We present a general approach for solving the point-cloud matching problem for the case of mildly nonlinear transformations. Our method quickly finds a coarse approximation of the solution by exploring a reduced set of ...
  • Combining geometric and appearance priors for robust homography estimation 

    Serradell, Eduard; Özuysa, Mustafa; Lepetit, Vincent; Fua, Pascal; Moreno-Noguer, Francesc (Springer, 2010)
    Conference report

    Abstract. The homography between pairs of images are typically computed from the correspondence of keypoints, which are established by using image descriptors. When these descriptors are not reliable, either because of ...
  • Exploring ambiguities for monocular non-rigid shape estimation 

    Moreno-Noguer, Francesc; Porta Pleite, Josep Maria; Fua, Pascal (Springer, 2010)
    Conference report
    Open Access
    Recovering the 3D shape of deformable surfaces from single images is difficult because many different shapes have very similar projections. This is commonly addressed by restricting the set of possible shapes to linear ...
  • Reconstructing geometrically consistent tree structures from noisy images 

    Türetken, Engin; Blum, Christian; González, Germán; Fua, Pascal (2010-09)
    Article
    Restricted access - publisher's policy
    We present a novel approach to fully automated reconstruction of tree structures in noisy 2D images. Unlike in earlier approaches, we explicitly handle crossovers and bifurcation points, and impose geometric constraints ...
  • Robust elastic 2D/3D geometric graph matching 

    Serradell, Eduard; Kybic, J.; Moreno-Noguer, Francesc; Fua, Pascal (2012)
    Conference report
    Open Access
    We present an algorithm for geometric matching of graphs embedded in 2D or 3D space. It is applicable for registering any graph-like structures appearing in biomedical images, such as blood vessels, pulmonary bronchi, ...
  • Robust non-rigid registration of 2D and 3D graphs 

    Serradell, Eduard; Glowacki, Przemyslaw; Jan, Kybic; Moreno-Noguer, Francesc; Fua, Pascal (2012)
    Conference report
    Open Access
    We present a new approach to matching graphs embedded in R2 or R3. Unlike earlier methods, our approach does not rely on the similarity of local appearance features, does not require an initial alignment, can handle partial ...
  • Simultaneous pose, correspondence and non-rigid shape 

    Sánchez-Riera, Jordi; Ostlund, Jonas; Fua, Pascal; Moreno-Noguer, Francesc (2010)
    Conference report
    Restricted access - publisher's policy
    Recent works have shown that 3D shape of non-rigid surfaces can be accurately retrieved from a single image given a set of 3D-to-2D correspondences between that image and another one for which the shape is known. However, ...
  • Stochastic exploration of ambiguities for nonrigid shape recovery 

    Moreno-Noguer, Francesc; Fua, Pascal (2013)
    Article
    Open Access
    Recovering the 3D shape of deformable surfaces from single images is known to be a highly ambiguous problem because many different shapes may have very similar projections. This is commonly addressed by restricting the set ...
