Porosity characterization on FIB images

The processed images are from FIB (Focused Ion Beam) microscopy. The purpose here was to characterize porosities in a nuclear material.

Porosity segmentation on a nuclear material

The analysis was processed on a ROI extracted from the whole volume.

The characterization steps included

  • aligning the volume plans,
  • intensity correction,
  • denoising the ROI,
  • material binarization,
  • hole separation,
  • labelizing the holes.


In addition to assinging an unique label to each hole, it is also possible to compute measures on these elements.
