Appendix 3—table 1. Epithelial Cell Benchmark results.

We compare PlantSeg to four other methods using the standard SEG metric (Maška et al., 2014) calculated as the mean of the Jaccard indices between the reference and the segmented cells in a given movie (higher is better). Mean and standard deviation of the SEG score are reported for peripodial (three movies) and proper disc (five movies) cells. Additionally we report the scores of PlantSeg pipeline executed with a network trained explicitly on the epithelial cell dataset (last row).
