A clustering algorithm for radiosity in complex environments
We present an approach for accelerating hierarchical radiosity by clustering objects. Previous approaches constructed effective hierarchies by subdividing surfaces, but could not ...

Coding the Wavelet Spatial Orientation Tree with Low Computational Complexity
ct A very fast, low complexity algorithm for resolution scalable and random access decoding is presented. The algorithm is based on AGP (Alphabet and Group Partitioning) [1], where...

A Typed Process Calculus for Fine-Grained Resource Access Control in Distributed Computation
We propose the πD -calculus, a process calculus that can flexibly model fine-grained control of resource access in distributed computation, with a type system that statically pr...

Fast Feldkamp algorithm for cone-beam computer tomography
We propose a new fast Feldkamp algorithm for 3-D cone beam tomography with a circular source trajectory. The algorithm is an extension of our recent fast native 2-D fan-beam recon...
