      abstract     = {In this paper, we propose an averaging method for expert
                      segmentation proposals of microbial organisms, resulting in
                      a smooth, naturally looking segmentation ground truth. The
                      approach exploits a geometrical property of the majority of
                      the organisms - star-shapedness - and is based on contour
                      averaging in polar space. It is robust and computationally
                      efficient, where robustness is due to the absence of
                      tuneable parameters. Moreover, the algorithm preserves the
                      uncertainty (in terms of the standard deviation) of the
                      experts' opinion, which allows to introduce an
                      uncertainty-aware metric for estimation of the segmentation
                      quality. This metric emphasizes the influence of ground
                      truth regions with low variance. We study the performance of
                      the proposed averaging method on time-lapse microscopy data
                      of Corynebacterium glutamicum and the uncertainty-aware
                      metric on synthetic data.},
