Symmetric Trellis Coded Vector Quantization
We present here design techniques for trellis-coded vector quantizers with symmetric codebooks that facilitate lowcomplexity quantization as well as partitioning into equiprobable ...

Pattern-based Compression of Text Images
We suggest a novel approach for compressing images of text documents based on building up a simple derived font from patterns in the image, and present the results of a prototype ...

The Invariants of the Clifford Groups
The automorphism group of the Barnes-Wall lattice Lm in dimension 2m (m = 3) is a subgroup of index 2 in a certain "Clifford group" Cm of structure 21+2m + .O+ (2m, 2). ...

On the Implementation of Minimum-Redundancy Prefix Codes
Abstract--Minimum redundancy coding (also known as Huffman coding) is one of the enduring techniques of data compression. Many efforts have been made to improve the efficiency of m...
