Using topographical images obtained by confocal laser scanning microscopy, the topography of brittle fracture surfaces and wire-eroded surfaces was quantified. The global topometry values show a significant dependency on the imaging conditions and on the computing algorithm. An algorithm was developed and implemented for the automatic detection and measuring of feature-related parameters in topographies, which uses methods of computational geometry. The software was tested using brittle fracture surfaces of steel.
