Affine invariant texture signatures
In this paper, we develop a new approach for texture classification independent of affine transforms. Based on spectral representation of texture images under affine transform, an...

An Algebraic Approach to Rule-Based Information Extraction
Traditional approaches to rule-based information extraction (IE) have primarily been based on regular expression grammars. However, these grammar-based systems have difficulty scal...

Generating Vulnerability Signatures for String Manipulating Programs Using Automata-Based Forward and Backward Symbolic Analyses
Given a program and an attack pattern (specified as a regular expression), we automatically generate string-based vulnerability signatures, i.e., a characterization that includes...

A graph-theoretic approach to extract storylines from search results
We present a graph-theoretic approach to discover storylines from search results. Storylines are windows that offer glimpses into interesting themes latent among the top search re...
