Local feature size

Local feature size refers to several related concepts in computer graphics and computational geometry for measuring the size of a geometric object near a particular point.

• Given a smooth manifold $M$, the local feature size at any point $x\in M$ is the distance between $x$ and the medial axis of $M$.
• Given a planar straight-line graph, the local feature size at any point $x$ is the radius of the smallest closed ball centered at $x$ which intersects any two disjoint features (vertices or edges) of the graph.
