Point Feature Descriptor via Directional Partition of Unity on Maps
Phan Thanh An, Phiet DauThe
We develop a functional-analytic framework for smooth directional point descriptors in GPS-free map-based localization. Given a query point in a map $\mathcal{M} \subs…
Multiple Shooting Approach for Finding Approximately Shortest Paths for Autonomous Robots in Unknown Environments in 2D
Phan Thanh An, Nguyen Thi Le
An autonomous robot with a limited vision range finds a path to the goal in an unknown environment in 2D avoiding polygonal obstacles. In the process of discovering the environment…
Blaschke and Separation Theorems for Orthogonally Convex Sets
Phan Thanh An, Nguyen Thi Le
In this paper, we deal with analytic and geometric properties of orthogonally convex sets. We establish a Blaschke-type theorem for path-connected and orthogonally convex sets in t…
Finding Approximately Convex Ropes in the Plane
Le Hong Trang, Nguyen Thi Le, Phan Thanh An
The convex rope problem is to find a counterclockwise or clockwise convex rope starting at the vertex a and ending at the vertex b of a simple polygon P, where a is a vertex of the…
