Robust Topological Features for Deformation Invariant Image Matching
Local photometric descriptors are a crucial low level component of numerous computer vision algorithms. In practice, these descriptors are constructed to be invariant to a class o...

Meta-Mesh Span Restoration and Increased Lightpath Routing in Sparse Network Topologies
— Prior work has shown that network capacity efficiency decreases significantly as a network’s topology becomes sparse. Meta-mesh restoration was proposed in prior work as a me...

Effects of topology on local throughput-capacity of ad hoc networks
—Most publications on the capacity and performance of wireless ad hoc networks share the underlying assumption of a uniform random distribution of nodes. In this paper, we study ...

Topology Inference for a Vision-Based Sensor Network
In this paper we describe a technique to infer the topology and connectivity information of a network of cameras based on observed motion in the environment. While the technique c...
