• The Hamilton-Jacobi skeleton 

      Siddiqi, Kaleem; Bouix, Sylvain; Tannenbaum, Allen R.; Zucker, Steven W. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 1999-09)
      The eikonal equation and variants of it are of significant interest for problems in computer vision and image processing. It is the basis for continuous versions of mathematical morphology, stereo, shape-from-shading and ...
    • On the Evolution of the Skeleton 

      August, Jonas; Tannenbaum, Allen R.; Zucker, Steven W. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 1999-09)
      It is commonly held that skeleton variation due to noise is unmanageable. It is also believed that smoothing, invoked to combat noise, creates no new structures, as in the causality principle for smoothing images. We ...
    • Stereo disparity and L ¹ minimization 

      Kumar, Arun; Haker, Steven; Vogel, Curt; Tannenbaum, Allen R.; Zucker, Steven W. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 1997-12)
      In this note, we employ an L ¹ PDE approach for stereo disparity. This approach has the nice feature of preserving edges in the computation. Our numerical method is based on the techniques for the analysis of curves ...
