      Extreme feature regions are increasingly critical for many image matching applications on affine image-pairs. In this paper, we focus on the time-consumption and accuracy of using extreme feature regions to do the ...
    • Extreme Model Simplification for Forest Rendering 

      Fuhrmann, Anton L.; Umlauf, Eike; Mantler, Stephan (The Eurographics Association, 2005)
      Models of large forest scenes are of a geometric complexity that surpasses even the capabilities of current high end graphics hardware. We propose an extreme simplification method which allows us to render such scenes in ...
    • Extrinsic Self-Calibration of Time-of-Flight Cameras using a Combination of 3D and Intensity Descriptors 

      Schmidt, Jörn; Brückner, Marcel; Denzler, Joachim (The Eurographics Association, 2011)
      Time-of-Flight (ToF) cameras are able to simultaneously record intensity and depth images at a high frequency. Many applications require images that are recorded from different viewpoints. In order to consolidate the ...
