Channel adapted multiple description coding scheme using wavelet transform
A challenge of image communication over unreliable channels is to achieve good compression rates and be effective in presence of channel failures. In this work we use the Multiple...

Directly Addressable Variable-Length Codes
We introduce a symbol reordering technique that implicitly synchronizes variable-length codes, such that it is possible to directly access the i-th codeword without need of any sam...

Minimum cost distributed source coding over a network
— This work considers the problem of transmitting multiple compressible sources over a network with minimum cost. The problem is complicated by the fact that the description of t...

An efficient bit allocation for compressing normal meshes with an error-driven quantization
We propose a new wavelet compression algorithm based on the rate-distortion optimization for densely sampled triangular meshes. Exploiting the normal remesher of Guskov et al., th...

Design of a decompressor engine on a SPARC processor
Code compression, initially conceived as an effective technique to reduce code size in embedded systems, today also brings advantages in terms of performance and energy consumpti...
