Indexing planar point quartets via geometric attributes
An index is devised to support position-independent search for images containing quartets of icons. Point quartets exist that do not unambiguously map to quadrilaterals, however, ...

Uncalibrated 1D projective camera and 3D affine reconstruction of lines
We describe a linear algorithm to recover 30 afJine slzape/niotionfrom line correspondences over three views with uncalibrated afine cameras. The key idea is the introduction of a...

Efficient and small representation of line arrangements with applications
This paper addresses the problem of lossy compression of arrangements. Given an arrangement of n lines in the plane, we show how to construct another arrangement consisting of man...

A note concerning the closest point pair algorithm
An algorithm, described by Sedgewick, finds the distance between the closest pair of n given points in a plane using a variant of mergesort. This takes O(n log n) time. To prove t...

Cuttings for Disks and Axis-Aligned Rectangles
We present new asymptotically tight bounds on cuttings, a fundamental data structure in computational geometry. For n objects in space and a parameter r ∈ N, an 1 r -cutting is ...
