    • Active Testing Search for Point Cloud Matching 

      Author: Amável Pinheiro, Miguel; Sznitman, Raphael; Serradell, Eduard; Kybic, Jan; Moreno-Noguer, Francesc; Fua, Pascal
      (Springer, 2013)
      We present a general approach for solving the point-cloud matching problem for the case of mildly nonlinear transformations. Our method quickly nds a coarse approximation of the solution by exploring a reduced set of ...
    • Bootstrap Resampling for Image Registration Uncertainty Estimation Without Ground Truth 

      Author: Kybic, Jan
      (IEEE, 2010-01)
      We address the problem of estimating the uncertainty of pixel based image registration algorithms, given just the two images to be registered, for cases when no ground truth data is available. Our novel method uses bootstrap ...
    • Fast no ground truth image registration accuracy evaluation: Comparison of bootstrap and Hessian approaches 

      Author: Kybic, Jan
      (IEEE, 2008-05)
      Image registration algorithms provide a displacement field between two images. We consider the problem of estimating accuracy of the calculated displacement field from the input images only and without assuming any specific ...
    • Fast Parametric Elastic Image Registration 

      Author: Kybic, Jan; Unser, Michael
      (IEEE, 2003-11)
      We present an algorithm for fast elastic multidimensional intensity-based image registration with a parametric model of the deformation. It is fully automatic in its default mode of operation. In the case of hard real-world ...
    • Robust elastic 2D/3D geometric graph matching 

      Author: Serradell, Eduard; Kybic, Jan; Moreno-Noguer, Francesc; Fua, Pascal
      (SPIE, 2012)
      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, nerve ...
    • Robustní a rychlá registrace obrazů metodou "Local All Pass" 

      Author: David Kunz; Supervisor: Kybic Jan; Opponent: Sovka Pavel
      (České vysoké učení technické v Praze. Vypočetní a informační centrum.Czech Technical University in Prague. Computing and Information Centre., 2020-08-26)
      Registrace obrázků je důležitou součástí mnoha praktických aplikací v poli lékařského zobrazování, v počítačovém vidění, v kartografii atd. V této bakalářské práci představuji novou metodu registrace založenou na metodě ...
    • Unwarping of Unidirectionally Distorted EPI Images 

      Author: Kybic, Jan; Thévenaz, Philippe; Nirkko, Arto; Unser, Michael
      (IEEE, 2000-02)
      Echo-planar imaging (EPI) is a fast nuclear magnetic resonance imaging (MRI) method. Unfortunately, local magnetic field inhomogeneities induced mainly by the subject's presence cause significant geometrical distortion, ...
