Figure 3. The distributions of TP+, TP- and BG when using 10%
labeled data on COCO. ‘TP+’ means that the estimated instance
has the same class ID as the ground-truth (GT) and the IOU of
BBox is above 0.5. ‘TP-’ means that the estimated instance has
the same class ID as GT but the IOU of BBox is below 0.5. ‘BG’
means that the estimated instance belongs to the background or
has wrong class ID.
