Shortest Paths in Two Intersecting Pencils of Lines
Suppose one has a line arrangement and one wants to find a shortest path from one point lying on a line of the arrangement to another such point. We look at a special case: the a...

Polygonizing Non-Uniformly Distributed 3D Points by Advancing Mesh Frontiers
30 digitization devices produce very large sets of 3 0 points sampled from the suqaces of the objects being scanned. A mesh construction procedure needs to be:upplied to derive po...

Point Cloud Skeletons via Laplacian Based Contraction
—We present an algorithm for curve skeleton extraction via Laplacian-based contraction. Our algorithm can be applied to surfaces with boundaries, polygon soups, and point clouds....

Reconstruction from Six-Point Sequences
An algorithm is given for computing projective structure from a set of six points seen in a sequence of many images. The method is based on the notion of duality between cameras a...

Quantum Separation of Local Search and Fixed Point Computation
In this paper, we give a lower bound of (n(d-1)/2 ) on the quantum query complexity for finding a fixed point of a discrete Brouwer function over grid [1 : n]d . Our bound is near...
