(English Abstract)
Optical Diffraction Tomography is a technique used to acquire a three-dimensional volumetric image data set of living cells without additional treatment. While there has been various achievements made in the imaging technique, not yet much in those tools to support analysis based on the acquired image data. In this paper, we propose an automated lipid droplet tracking method which can be applied to 3D cell images using optical flow. The proposed method estimates the motion of lipid droplet from optical flow, and enables individual tracking of all lipid droplets present in the image at once through lipid droplet position estimation and labeling process. Additionally, we implemented the tracking method in three ways to resolve the accumulated errors from the algorithm as the tracking progresses. The performance was then compared their qualitatively and quantitatively using HeLa cell and hepatocyte cell image data. As a result, we found that per-frame tracking method, which traces with mapping lipid droplet positions, was the optimal tracking method suitable for optical diffraction tomography images.
