Document retrieval and web search engines index large quantities of text. The static costs associated with storing the index can be traded against dynamic costs associated with us...
We have developed a scalable image compression scheme with a good performance-complexity trade-off. Like JPEG, it is based on the 8 × 8 block discrete cosine transform (DCT), but...
In this paper we present a mesh compression method based on a multiresolution decomposition whose detail coefficients have a compact representation and thus smaller entropy than t...
On sparse images, contiguous runs of identical symbols often occur in the same coding context. This paper proposes a model for efficiently encoding such runs in a twodimensional s...
This paper describes an experimental system for classroom-based tele-education based on IP multicast. It gives an overview of the system and describes how the system is designed t...
