Space-efficient dynamic orthogonal point location, segment intersection, and range reporting
We describe an asymptotically optimal data-structure for dynamic point location for horizontal segments. For n line-segments, queries take O(log n) time, updates take O(log n) amo...

Robust Detection of Corners and Corner-line Links in Images
We define corner points in an image as the intersections among detected straight line segments, and propose an algorithm that detects corners from such a definition. Our corner det...

Spanners for Geometric Intersection Graphs
A ball graph is an intersection graph of a set of balls with arbitrary radii. Given a real number t > 1, we say that a subgraph G′ of a graph G is a t-spanner of G, if for eve...

Preserving Ambiguities in Generation via Automata Intersection
We discuss the problem of generating text that preserves certain ambiguities, a capability that is useful in applications such as machine translation. We show that it is relativel...

Theory and implementation of path planning by negotiation for decentralized agents
This paper presents a cooperative decentralized path-planning algorithm for a group of autonomous agents that provides guaranteed collisionfree trajectories in real-time. The algo...
