A Wolfram Mathematica image processing code for automated analysis of metal alloy solidification in Hele-Shaw cells, originally designed for dynamic X-ray imaging applications.

ACHTUNG: this Mathematica code uses MATLink
http://matlink.org/
and couples the code to the MATLAB engine to use this BM3D implementation (currently v3.0.9):
https://webpages.tuni.fi/foi/GCF-BM3D/index.html#ref_software
Both MATLink and MATLAB are currently hard requirements.

Current functionality:

• Liquid/solid domain segmentation
• Liquid cavity & channel (chimney) detection
• Solidification front derivation
• Solute concentration measurements above the solidification front and in the liquid domain
• Deriving the dynamics of the solidification front shape and its motion
• Multi-level segmentation of convective plumes
• Dendrite skeleton detection in the solid domain & orientation analysis
• Decomposotion of the solidified structures into grains by orientation & distance

Features under development:

• Primary dendrite spacing measurements
• Deriving the local thickness of the solidified structures
• Optical flow velocimetry within the liquid domain
• Improving performance by offloading some image filtering tasks to a GPU (a CPU-only version will be kept as a separate branch)
