Network Topology Inference Based on End-to-End Measurements
Abstract--We consider using traceroute-like end-to-end measurement to infer the underlay topology for a group of hosts. One major issue is the measurement cost. Given hosts in an a...

Globally Optimal Affine Epipolar Geometry from Apparent Contours
We study the problem of estimating the epipolar geometry from apparent contours of smooth curved surfaces with affine camera models. Since apparent contours are viewpoint depend...
