Multiple-Description Coding by Dithered Delta-Sigma Quantization
We address the connection between the multiple-description (MD) problem and Delta-Sigma quantization. The inherent redundancy due to oversampling in Delta-Sigma quantization, and ...

Simple Linear-Time Off-Line Text Compression by Longest-First Substitution
We consider grammar based text compression with longest first substitution, where non-overlapping occurrences of a longest repeating substring of the input text are replaced by a ...

Lossless and Near-Lossless Audio Compression Using Integer-Reversible Modulated Lapped Transforms
We present a simple lossless audio codec, composed of an integer-reversible modulated lapped transform (MLT) followed by a backward-adaptive run-length/Golomb-Rice (RLGR) encoder....

Joint Optimization of Distributed Broadcast Quantization Systems for Classification
We develop a simulated annealing technique to jointly optimize a distributed quantization structure meant to maximize the asymptotic error exponent of a downstream classifier or d...

Type-Based Compression of XML Data
The extensible markup language XML has become indispensable in many areas, but a significant disadvantage is its size: tagging a set of data increases the space needed to store it...

Compressed Delta Encoding for LZSS Encoded Files
We explore the Full Compressed Delta Encoding problem in compressed texts, defined as the problem of constructing a delta file directly from the two given compressed files, withou...
