Path classification count for different tracking approaches.

The first column shows the reference data, i.e. the manually determined number of paths and mitoses. Next, the number of path fragments is given (cf. section IV: first validation/path fragments). Connecting path fragments with naive tracking results in the numbers, displayed in the 3 rd column (cf. section IV: naive tracking). Validating the path continuations leads to significantly less complete paths, the reliability of which is, however, much higher (rightmost column).
