Detecting Stellar Streams in the Halos of Galaxies with Voronoi Tessellations
Galaxy formation models oriented towards a ΛCDM cosmology envision galaxies as being built through the accretion of dwarf galaxies. Such galaxy accretion should appear as tidally...

Ordered multisignatures and identity-based sequential aggregate signatures, with applications to secure routing
We construct two new multiparty digital signature schemes that allow multiple signers to sequentially produce a compact, fixed-length signature. First, we introduce a new primiti...

Human Action Recognition Using Distribution of Oriented Rectangular Patches
We describe a “bag-of-rectangles” method for representing and recognizing human actions in videos. In this method, each human pose in an action sequence is represented by orien...

Fitting Subdivision Surface Models to Noisy and Incomplete 3-D Data
Abstract. We describe an algorithm for fitting a Catmull-Clark subdivision surface model to an unstructured, incomplete and noisy data set. We complete the large missing data regi...

Function-based shape modeling and visualization in X3D
In this paper, a function-based extension of Extensible 3D (X3D) is proposed. The extension allows authors to use analytical functions to define geometry, color, 3D texture as wel...
