    Constructing Reeb graphs using cylinder maps
    Download  drona.csa.iisc.ernet.in
    The Reeb graph of a scalar function represents the evolution of the topology of its level sets. In this video, we describe a near-optimal output-sensitive algorithm for computing ...

    Topological Parsing
    Download  www.cs.toronto.edu
    We present a new grammar formalism for parsing with freer word-order languages, motivated by recent linguistic research in German and the Slavic languages. Unlike CFGs, these gram...

    3D face tracking and expression inference from a 2D sequence using manifold learning
    Download  iris.usc.edu
    We propose a person-dependent, manifold-based approach for modeling and tracking rigid and nonrigid 3D facial deformations from a monocular video sequence. The rigid and nonrigid ...

    Lung Nodule Growth Analysis from 3D CT Data with a Coupled Segmentation and Registration Framework
    Download  www.med.unc.edu
    In this paper we propose a new framework to simultaneously segment and register lung and tumor in serial CT data. Our method assumes nonrigid transformation on lung deformation an...

    High-Resolution Volumetric Computation of Offset Surfaces with Feature Preservation
    Download  www-i8.informatik.rwth-aachen.de
    We present a new algorithm for the efficient and reliable generation of offset surfaces for polygonal meshes. The algorithm is robust with respect to degenerate configurations and...
