      Optical coherence tomography (OCT) enables noninvasive high-resolution 3D imaging of the human retina and thus, plays a fundamental role in detecting a wide range of ocular diseases. Despite OCT's diagnostic value, managing ...
    • Visual Analysis of Public Transport Vehicle Movement 

      Wörner, Michael; Ertl, Thomas (The Eurographics Association, 2012)
      Public transport vehicles record detailed operational logs. In major networks, this quickly amounts to massive datasets. Traditionally, these are analysed only using statistical tools, yet they show great potential for the ...
    • Visual Analysis of Relations in Attributed Time-Series Data 

      Steiger, Martin; Bernard, Jürgen; Schader, Philipp; Kohlhammer, Jörn (The Eurographics Association, 2015)
      In this paper, we present visual-interactive techniques for revealing relations between two co-existing multivariate feature spaces. Such data is generated, for example, by sensor networks characterized by a set of ...
    • Visual Analysis of Tracts of Homozygosity in Human Genome 

      Reber, Sean; Zhao, Ye; Zhang, Li; Orloff, Mohammed; Eng, Charis (The Eurographics Association, 2013)
      We propose a new visual analytics system designed for genetic researchers to study genome-wide homozygosity regions. Finding significant tracts of homozygosity (TOH) using single nucleotide polymorphisms (SNPs) from a ...
    • Visual Analysis of User Behaviour in Pay-Per-Bid Auctions 

      Walker, Rick; Cenydd, Llyr ap; Pop, Serban; Roberts, Jonathan C. (The Eurographics Association, 2011)
      In pay-per-bid auctions, placing a bid costs a fee, and only raises the price of the item by a small increment. At the conclusion of the auction, the last bidder wins, and the price paid by the winning bidder is subsidised ...
    • Visual Analytics and Uncertainty: Its Not About the Data 

      MacEachren, Alan M. (The Eurographics Association, 2015)
      Uncertainty visualization research has a long history, with contributions from scientific, information, geo-graphic and other visualization perspectives as well as from cognitive and HCI perspectives. But we still do not ...
