Quality of the human gold standard segmentation (MSEG GT ), detection (MDET GT ) and tracking (MTRA GT ) annotations, and of the fused silver standard segmentation (SEG ST and DET ST ) annotations, relative to the gold truth for all available datasets. Following the coloring scheme of Fig. 2 , the color code in this table illustrates the relative difficulty of the annotation task, reflected by the level of agreement between annotators (gold standard annotations) and the quality of the silver standard annotations. See the Quality of annotations and human-level performance section in Methods for an expanded explanation of how the values were calculated. For the definitions of the dataset names please see the Fig. 2 legend.
