Student Work

Our group was in close contact with ETH Zurich and other universities and consistently supervised student work. Term papers, internships as well as diploma and master theses were successfully completed and expanded our expertise.

We do not offer student projects any more.

Former list of available projects

Additionally, we were interested in the following topics:

  • Expansion of color management to special colors
  • Color seperation concepts for special colors
  • Best work space for gamut mapping
  • Characterization of color print processes
    • Colorimetric measurement of selected raster cells
    • Estimation of non-measured raster cells
  • Preference analysis with MacAdam ellipses
  • 3D animation of simple objects in parametric geometry
  • Optimizing OCR concepts for libraries
  • Upscaling of images
  • Image compression with Tschebyschew polynomials
  • Simulation of interference colors in textiles

Ursina Caluori: An Alternative to Color Management Systems

July to December 2007

Color management systems offer a high degree of flexibility in dealing with different devices, however, define a complex workflow, which in some color spaces are no longer reversible. This work deals with the attempt to link together these stations for an RGB image for a particular device.

Soo-Jung Lee: Frequency Modulation for Laser Printer

August to November 2007

Compared to amplitude modulated raster processes (AM), frequent modulated raster processes (FM) have the advantage to utilize the resolution of a device better. Due to dotgain however, the color accuracy, especially at high resolutions, isn't guaranteed. The work of Soo-Jung addresses this problem and tries to compensate the resulting dotgain of an image with a modification of the Floyd-Steinberg algorithm.

Tobias Stamm: Subsurface Scattering Effects in Halftoning

November 2006 to April 2007

The effect images appearing darker when printed on paper is described by dotgain. Roughly, a distinciton is made between physical dotgain caused by the printing device and the optical dotgain which results from the physical- geometrical properties of light. This work attempts to particularly emulate the optical dotgain via simulation technology.
