| Outline of Final Research Achievements |
In this research, we aimed at developing the methods for automating the detection and tracking of cell regions in 4D live-cell imaging data. Cells in 4D live-cell imaging data are often imaged as ellipsoidal shapes and are densely distributed. For this data, standard methods usually fail to automatic tracking because of cell-switching and coalescence of tracked positions. To address this issue, we utilized typical characteristics in 4D live-cell imaging data; movements of nearly-located cells are strongly correlated. By using the characteristics used as the information for predicting cells' positions, we succeeded to improve tracking performance drastically. The software developed in this research is being distributed on the project website.
