Capillary length estimation (Microscopy & Microanalysis 2013)

Three types of capillary length estimation methods were compared:

  1. Stereological methods based on a computer generation of isotropic uniform random virtual test probes in 3D, either in the form of spatial grids of virtual “slicer” planes, or spherical probes.
  2. Automatic method employing a digital version of the Crofton relations using the Euler characteristic of planar sections of the binary image.
  3. Interactive “tracer” method for length measurement based on a manual delineation in 3D of the axes of capillary segments. The presented methods were compared in terms of their practical applicability, efficiency and precision.
