• Conformal Surface Parameterization for Texture Mapping 

      Haker, Steven; Angenent, Sigurd; Tannenbaum, Allen R.; Kikinis, Ron; Sapiro, Guillermo; Halle, Michael (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2000-04)
      We give an explicit method for mapping any simply connected surface onto the sphere in a manner which preserves angles. This technique relies on certain conformal mappings from differential geometry. Our method provides a ...
    • 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 ...
    • Nondistorting Flattening Maps and the 3-D Visualization of Colon CT Images 

      Haker, Steven; Angenent, Sigurd; Tannenbaum, Allen R.; Kikinis, Ron (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2000-07)
      Considers a novel three-dimensional (3-D) visualization technique based on surface flattening for virtual colonoscopy. Such visualization methods could be important in virtual colonoscopy because they have the potential ...
    • 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 ...
