Table 2.

Instance segmentation mask on COCO (Common Objects in Context) test-dev. FCIS was the winner of COCO 2016. FCIS+++ uses more mature technology. Mask R-CNN’s network segmentation accuracy has been substantially improved, and it is the benchmark for the 2017 segmentation network model. PAN, proposed in 2018, yielded excellent results; however, the network is complex, the amount of data is large, and it requires more time. MS R-CNN in 2019 yielded the best results. MR R-CNN is suitable for predicting large and medium-sized objects, while other indicators are close to the best value.
