Approximate Euclidean shortest paths amid convex obstacles

چکیده
We develop algorithms and data structures for the approximate Euclidean shortest path problem amid a set P of k convex obstacles in R and R, with a total of n faces. The running time of our algorithms is linear in n, and the size and query time of our data structure are independent of n. We follow a “core-set” based approach, i.e., we quickly compute a small sketch Q of P whose size is independent of n and then compute approximate shortest paths with respect

Coresets of obstacles in approximating Euclidean shortest path amid convex obstacles
Given a set P of non-intersecting polygonal obstacles in R defined with n vertices, we compute a sketch Ω of P whose size is independent of n. We utilize Ω to devise an algorithm to compute a (1 + )-approximate Euclidean shortest path between two points given with the description of P. When P comprises of convex polygonal obstacles, we devise a (2 + )approximation algorithm to efficiently answe...
متن کاملApproximate Shortest Paths in Simple Polyhedra
Introduction Minimal paths in volume images have raised interest in computer vision and image analysis (for example, [4, 5]). In medical image analysis, minimal paths were extracted in 3D images and applied to virtual endoscopy [5]. The existed approximation algorithms for 3D ESP calculations are not efficient, see, for example, [2, 6]. Recently, [1] proposes algorithms for calculating approxim...
متن کاملApproximate shortest paths in moderately anisotropic regions
We want to find an approximate shortest path for a point robot moving in a planar subdivision. Each face of the subdivision is associated with a convex distance function that has the following property: its unit disk contains a unit Euclidean disk, and is contained in a Euclidean disk with radius ρ. Obstacles are allowed, so there can be regions that the robot is not allowed to enter. We give a...
متن کاملGeneralized Unfoldings for Shortest Paths in Euclidean 3-Space
The problem of determining shortest paths in the presence of polyhedral obstacles between two points in Euclidean 3-space stems from the general problem of obtaining optimal coliision free paths in robot systems. For the special case when paths are constrained to the surfaces of 3-dimensional objects, simple planar unfoldings are used to obtain the shortest path. For the general case wben paths...
متن کاملA Nearly Optimal Algorithm for Finding L 1 Shortest Paths among Polygonal Obstacles in the Plane
Given a set of h pairwise disjoint polygonal obstacles of totally n vertices in the plane, we study the problem of computing an L1 (or rectilinear) shortest path between two points avoiding the obstacles. Previously, this problem has been solved in O(n log n) time and O(n) space, or alternatively in O(n + h log n) time and O(n + h log h) space. A lower bound of Ω(n + h log h) time and Ω(n) spac...
