Abstract

The way that information propagates in neural networks is of great importance. In this paper, we propose Path Aggregation Network (PANet) aiming at boosting information flow in proposal-based instance segmentation framework. Specifically, we enhance the entire feature hierarchy with accurate localization signals in lower layers by bottom-up path augmentation, which shortens the information path between lower layers and topmost feature. We present adaptive feature pooling, which links feature grid and all feature levels to make useful information in each level propagate directly to following proposal subnetworks. A complementary branch capturing different views for each proposal is created to further improve mask prediction. These improvements are simple to implement, with subtle extra computational overhead. Yet they are useful and make our PANet reach the 1st place in the COCO 2017 Challenge Instance Segmentation task and the 2nd place in Object Detection task without large-batch training. PANet is also state-of-the-art on MVD and Cityscapes.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • PANet has a better fusion effect than FPN.

    “Therefore, PANet has a better fusion effect than FPN.”

    From A deep learning model for steel surface defect detection (2024) · cites this paper as [22]

  • For fair comparison, original FPN and PANet are repeated multiple times and all convs are replaced with depthwise separable convs, same as BiFPN.

    “Notably, the original FPN [23] and PANet [26] only have one top-down or bottom-up flow, but for fair comparison, here we repeat each of them multiple times and replace all convs with depthwise separable convs, which is the same as BiFPN.”

    From EfficientDet: Scalable and Efficient Object Detection (2019) · cites this paper as [26]

  • PANet adopts a bottom-up branch to upload underlying information in fewer residual nodes to enhance the semantic information of low-level feature maps.

    “PANet [9] adopts another bottom-up branch to make the underlying information uploaded in fewer residual nodes to enhance the semantic information of low-level feature maps.”
  • The CSP and PANet neck with an SPP block generates feature pyramids that help the overall network generalize objects of different scales and sizes.

    “This neck generates feature pyramids that help the overall network to generalize objects of different scales and sizes.”
  • Using feature pyramids, PANet, and SPP blocks improves object identification on unseen data.

    “Using feature pyramids, PANet, and SPP blocks improves object identification on unseen data as well.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
