Volume rendering of separate pieces of gravel. The false coloring demonstrates the segmentation of individual grains. μ-CT ProCon XRay.
MAVI or ToolIP+MAVIkit can be used to segment particles in three-dimensional image data and determine the size and shape distributions of these objects. The length, width and height of complex-shaped particles can be robustly obtained from the edge lengths of the minimum enveloping cuboid.
Particularly pointed particles or systems of particles of very different sizes cannot always be separated directly without errors. A random forest that recognizes and joins splinters helps here.
