Spiraling Edge: Fast Surface Reconstruction from Partially Organized Sample Points
Many applications produce three-dimensional points that must be further processed to generate a surface. Surface reconstruction algorithms that start with a set of unorganized poi...

Exact Cellular Decompositions in Terms of Critical Points of Morse Functions
Exact cellular decompositions are structures that globally encode the topology of a robot's free space, while locally describing the free space's geometry. These structu...

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....

Vanishing point detection for road detection
Given a single image of an arbitrary road, that may not be well-paved, or have clearly delineated edges, or some a priori known color or texture distribution, is it possible for...

Reconstructing Manifold and Non-Manifold Surfaces from Point Clouds
This paper presents a novel approach for surface reconstruction from point clouds. The proposed technique is general in the sense that it naturally handles both manifold and non-m...
