    • Construction of Precise Local Affine Frames 

      Author: Mikulik, Andrej; Matas, Jiří; Perd’och, Michal; Chum, Ondřej
      (IEEE, 2010-08)
      We propose a novel method for the refinement of Maximally Stable Extremal Region (MSER) boundaries to sub-pixel precision by taking into account the intensity function in the 2 × 2 neighborhood of the contour points. The ...
    • Discrete curvature calculation for fast level set segmentation 

      Author: Kybic, Jan; Krátký, Jakub
      (IEEE, 2009-11)
      Fast level set methods replace continuous PDEs by a discrete formulation, improving the execution times. The regularization in fast level set methods was so far handled indirectly via level set function smoothing. We propose ...
