Algorithm for the simultaneous phase separation and particle tracking for vortex cavitation.
Based on the fish tracking algorithm developed by K. Muller (https://gitlab.tudelft.nl/kmuller1).
The present tracking code has been adjusted to high particle displacements (4 times that of the inter-particle separation in pixels), necessary in order to ensure that the displacement measurement is accurate. It has been tested on the reconstruction and tracking of particles and bubbles around a vortex cavity generated by a NACA 66(2)-415 elliptical foil.
Requires pre-trained CNN model for vortex-cavity image segmentation. The training code has been provided. It remains rudimentary (but effective), until a more comprehensive image classification procedure is implemented.
