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 ...
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 ...
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 ...
