The main motivation for this work is to identify tissue loss and growth in kymographs of fluorescently labelled cell membranes in live Drosophila embryos. We propose a variational model based on mass conservation with a source term together with convective regularisation, discuss its numerical solution, and present experimental results. This is joint work with Nilankur Dutta, Jocelyn Étienne, and Carola-Bibiane Schönlieb.
