Recently, fully convolutional instance segmentation methods have drawn much attention as they are often simpler and more efficient than two-stage approaches like Mask R-CNN. To date, almost all such approaches fall behind the two-stage Mask R-CNN method in mask precision when models have similar computation complexity, leaving great room for improvement.\n  In this work, we achieve improved mask prediction by effectively combining instance-level information with semantic information with lower-level fine-granularity.
