Combined Spatial and Subband Block Coding of Images
This paper describes a low-memory cache efficient Hybrid Block Coder (HBC) for images in which an image subband decomposition is partitioned into a combination of spatial blocks a...

Maintaining Spatial Data Sets in Distributed-Memory Machines
We propose a distributed data structure for maintaining spatial data sets on message-passing, distributed memory machines. The data structure is based on orthogonal bisection tree...

Edge preserving spatially varying mixtures for image segmentation
A new hierarchical Bayesian model is proposed for image segmentation based on Gaussian mixture models (GMM) with a prior enforcing spatial smoothness. According to this prior, the...

A new approach to virtual design for spatial configuration problems
In this paper, we present a new framework for the use of Virtual Reality (VR) in engineering design for configuration applications. Traditional VR systems support the visual explo...
