• 3D Reconstruction of Underwater Structures 

      Beall, Chris; Lawrence, Brian J.; Ila, Viorela; Dellaert, Frank (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2010)
      Environmental change is a growing international concern, calling for the regular monitoring, studying and preserving of detailed information about the evolution of underwater ecosystems. For example, fragile coral reefs ...
    • Clustering Social Event Images using Kernel Canonical Correlation Analysis 

      Ahsan, Unaiza; Essa, Irfan (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2014-06)
      Sharing user experiences in form of photographs, tweets, text, audio and/or video has become commonplace in social networking websites. Browsing through large collections of social multimedia remains a cumbersome task. ...
    • Computerized Macular Pathology Diagnosis in Spectral Domain Optical Coherence Tomography Scans Based on Multiscale Texture and Shape Features 

      Liu, Yu-Ying; Ishikawa, Hiroshi; Chen, Mei; Wollstein, Gadi; Duker, Jay S.; Fujimoto, James G.; Schuman, Joel S.; Rehg, James M. (Georgia Institute of TechnologyAssociation for Research in Vision and Ophthalmology, 2011-10)
      To develop an automated method to identify the normal macula and three macular pathologies (macular hole [MH], macular edema [ME], and age-related macular degeneration [AMD]) from the fovea-centered cross sections in ...
    • Detecting and Matching Repeated Patterns for Automatic Geo-tagging in Urban Environments 

      Schindler, Grant; Krishnamurthy, Panchapagesan; Lublinerman, Roberto; Liu, Yanxi; Dellaert, Frank (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 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 ...
    • Discontinuous Seam-Carving for Video Retargeting 

      Grundmann, Matthias; Kwatra, Vivek; Han, Mei; Essa, Irfan (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2010-06)
      We introduce a new algorithm for video retargeting that uses discontinuous seam-carving in both space and time for resizing videos. Our algorithm relies on a novel appearance-based temporal coherence formulation that ...
    • Inferring Temporal Order of Images From 3D Structure 

      Schindler, Grant; Dellaert, Frank; Kang, Sing Bing (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 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 ...
    • Learning General Optical Flow Subspaces for Egomotion Estimation and Detection of Motion Anomalies 

      Roberts, Richard; Potthast, Christian; Dellaert, Frank (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2009)
      This paper deals with estimation of dense optical flow and ego-motion in a generalized imaging system by exploiting probabilistic linear subspace constraints on the flow. We deal with the extended motion of the imaging ...
    • Probabilistic Temporal Inference on Reconstructed 3D Scenes 

      Schindler, Grant; Dellaert, Frank (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 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 ...
