Tuesday, 01 November 2016, 15:00 at MR 14, Centre for Mathematical Sciences – In this talk we will consider optical flow on evolving surfaces which can be parametrised from the 2-sphere. Our main motivation is to estimate cell motion in time-lapse volumetric (4D) microscopy images depictinguorescently labelled cells of a live zebrafish embryo. We exploit the fact that the recorded cells float on …
