We describe an approach that tracks planar regions of scene text that can undergo arbitrary 3-D rigid motion and scale changes. Our approach computes homographies on blocks of contiguous frames…

This paper presents a new human-motion identification and segmentation algorithm from moving cameras. The algorithm is based on alignment error between pairs of moving object images. Pairs of object images…

We use the Sequitur algorithm to generate a context-free grammar which efficiently extracts repetitive sequences of commands executed by one user – which is mainly used to generate a profile of the…

In this paper, we report on a process language, PPL, that we have designed to serve as a bridge between a representation designed for execution and a representation designed for…

This paper explores the mixed-initiative issues arising in the Personalized Time Manager (PTIME) system. PTIME is a persistent assistant that builds on our previous work on a personalized calendar agent.

This paper presents ongoing work to build the Personalized Time Manager (PTIME) system, a persistent assistant that builds on our previous work on a personalized calendar agent.

We generated a TOEFL-like test using WordNet, containing thousands of questions and composed only of words occurring with sufficient corpus frequency to support sound distributional comparisons.

We introduce a novel algorithm, TOQR, for relaxing failed queries over databases, that is, over-constrained DNF queries that return an empty result.

We address the problem of learning a morphological automaton directly from a monolingual text corpus without recourse to additional resources.
