Bounds on the Covering Radius of Linear Codes
Asymptotically bounding the covering radius in terms of the dual distance is a well-studied problem. We will combine the polynomial approach with estimates of the distance distribu...

Data Compression of Correlated Non-Binary Sources Using Punctured Turbo Codes
We consider the case of two corr elated non-binary sources. Data compression is achieved by transforming the sequences of non-binary symbols into sequences of bits and then using ...

Less Redundant Codes for Variable Size Dictionaries
In this paper, we report work on a family of variable-length codes with less redundancy than the de facto flat code used in most of the variable size dynamic dictionary based comp...

Image Compression using an Efficient Edge Cartoon + Texture Model
Wavelet-based image coders optimally represent smooth regions and isolated point singularities. However, wavelet coders are less adept at representing perceptually important edge ...

Zero-Error Source Coding with Maximum Distortion Criterion
Let finite source and reproduction alphabets X and Y and a distortion measure d : X ? Y [0, ) be given. We study the minimum asymptotic rate required to describe a source distrib...

Optimized Edgebreaker Encoding for Large and Regular Triangle Meshes
We present a technique designed aiming to improve the compression of the Edgebreaker CLERS string for large and regular meshes, where regularity is understood as the compactness o...

On-Line Adaptation in Image Coding with a 2-D Tarp Filter
On-line adaptation to nonstationary distributions is essential to good performance in image coding. Fixed-size contexts (with adaptive tables) are also widely used, in conjunction...
