JPEG 2000 coding of color-quantized images
The efficiency of compressing color-quantized images using general purpose lossless image coding methods depends on the degree of smoothness of the index images. A wellknown and v...

A Formal Model of Memory Peculiarities for the Verification of Low-Level Operating-System Code
This paper presents our solutions to some problems we encountered in an ongoing attempt to verify the micro-hypervisor currently developed within the Robin project. The problems t...

The Complexity of Local List Decoding
We study the complexity of locally list-decoding binary error correcting codes with good parameters (that are polynomially related to information theoretic bounds). We show that co...

Coding Time-Varying Signals Using Sparse, Shift-Invariant Representations
A common way to represent a time series is to divide it into shortduration blocks, each of which is then represented by a set of basis functions. A limitation of this approach, ho...
