Purpose of the Study:
- To introduce a novel algorithm for tracking cells in 3D time-lapse microscopy data.
- To enable the tracking of microglia in 3D confocal time-lapse microscopy images.
Main Methods:
- The algorithm computes cosegmentations between component trees of individual time frames using tree-assignments.
- Implementation is available in the ct3d package.
Main Results:
- The novel algorithm successfully tracks cells in 3D time-lapse microscopy data.
