HomePage of Petra Wiederhold, research topics and projects.

Research areas and projects:

. some applications of digital image analysis:
  Processing and analysis of microscopic indentation images, acquired by a micro-indentation hardness test machine,
  joint project CINVESTAV - Universidad Veracruzana (UV), 2014 - 2018.
  Within this project, an annoted image data bank has been developed:
  CINVESTAV/UV   Vickers Indentation Images   Data Bank


. digital estimators of geometrical properties of 2D and 3D objects
(arc and curve length estimators, minimal perimeter polygon and related objects, surface area estimators of 3D objects)

. some problems from computational geometry
. thinning on cell complexes   (equivalently, on digital topological spaces)
. dimension functions for digital (topological) spaces
