Table 4 Comparison of CVAT and FastCAT. The tables show the reduction of annotation time of the domain experts. Tgca stands for the time gained compared to annotation with CVAT and is the reduction of workload in %. Video 1 and video 2 are not used for this analysis as the open-source data do not provide full colonoscopies, but just polyp sequences and therefore it is not possible to perform an appropriate comparison
