Other than producing bounding boxes, our network also outputs\nhigh-quality instance-level segments. Taking into account the\ncategory-independent property of each target, we design a single stage salient\ninstance segmentation framework, with a novel segmentation branch. Our new\nbranch regards not only local context inside each detection window but also its\nsurrounding context, enabling us to distinguish the instances in the same scope\neven with obstruction. Our network is end-to-end trainable and runs at a fast\nspeed (40 fps when processing an image with resolution 320x320). We evaluate\nour approach on a publicly available benchmark and show that it outperforms\nother alternative solutions. We also provide a thorough analysis of the design\nchoices to help readers better understand the functions of each part of our\nnetwork.
