In collaboration with the Leibniz Institute of Virology and the Center for Structural Systems biology, Helmholtz Imaging is working on a processing pipeline for plaque assays. Plaque Assays are used to e.g. estimate the virus concentration in a given sample. For this high resolution images of cell cultures which have been infected with a virus containing solution, have to be analysed, plaques (i.e. areas of dead cells) need to be identified (instance segmentation) and counted. The challenge in this collaboration is the aim to provide a broadly applicable solution, capable to deal with various cell cultures, and viruses.
