      Clustering plays an important role in many large-scale data analyses providing users with an overall understand- ing of their data. Nonetheless, clustering is not an easy task due to noisy features and outliers existing ...

    • Document Thumbnails with Variable Text Scaling 

      Stoffel, Andreas; Strobelt, Hendrik; Deussen, Oliver; Keim, Daniel A. (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Document reader applications usually offer an overview of the layout for each page as thumbnail views. Reading the text in these becomes impossible when the font size becomes very small. We improve the readability of these ...
