Probabilistic Temporal Inference on Reconstructed 3D Scenes
(Georgia Institute of Technology, 2010)
Modern structure from motion techniques are capable of building city-scale 3D reconstructions from large image collections, but have mostly ignored the problem of large-scale structural changes over time. We present a ...
Inferring Temporal Order of Images From 3D Structure
(Georgia Institute of Technology, 2007-06)
In this paper, we describe a technique to temporally sort a collection of photos that span many years. By reasoning about persistence of visible structures, we show how this sorting task can be formulated as a constraint ...
Detecting and Matching Repeated Patterns for Automatic Geo-tagging in Urban Environments
(Georgia Institute of Technology, 2008-06)
We present a novel method for automatically geo-tagging photographs of man-made environments via detection and matching of repeated patterns. Highly repetitive environments introduce numerous correspondence ambiguities and ...
