%description
A system that computes metrics to assess the segmentation accuracy of
geospatial data. These metrics calculate the discrepancy between segmented
and reference objects, and indicate the segmentation accuracy. For more
details on choosing evaluation metrics, we suggest seeing Costa et al.
(2018) <doi:10.1016/j.rse.2017.11.024> and Jozdani et al. (2020)
<doi:10.1016/j.isprsjprs.2020.01.002>.
