Decomposing a Simple Polygon into Trapezoids

Chazelle’s triangulation [1] forms today the common basis for linear-time Euclidean shortest path (ESP) calculations (where start and end point are given within a simple polygon). This paper provides an alternative method for subdividing a simple polygon into “basic shapes”, using trapezoids instead of triangles. The authors consider the presented method as being substantially simpler than the ...

Searching a Polygonal Region from the Boundary

Polygon search is the problem of nding unpredictable mobile intruders in a polygonal region using one or more mobile searchers with various levels of vision, where both the searcher and intruders are allowed to move freely within the region. In this paper we consider a variant of this problem, termed boundary search, in which a single searcher has to nd the intruders from the boundary of the re...

Covering a Polygonal Region by Ellipses

We study the problem of how to cover a polygonal region by a small number of axis–parallel ellipses. This question is well motivated by a special pattern recognition task where one has to identify ellipse shaped protein spots in 2–dimensional electrophoresis images. We present and discuss two algorithmic approaches solving this problem: a greedy brute force method and a linear programming formu...

Covering a polygonal region by rectangles

The problem of covering a compact canonical polygonal region, called target region, with a finite family of rectangles is considered. Tools for mathematical modeling of the problem are provided. Especially, a function, called Γ-function, is introduced which indicates whether the rectangles with respect to their configuration form a cover of the target region or not. The construction of the Γ-fu...

Packing Two Disks into a Polygonal Environment

Prosenjit Bose1, Pat Morin2, and Antoine Vigneron3 1 Carleton University. [email protected] 2 McGill University. [email protected] 3 Hong Kong University of Science and Technology. [email protected] Abstract. We consider the following problem. Given a polygon P , possibly with holes, and having n vertices, compute a pair of equal radius disks that do not intersect each other, are contained i...
