Dpnet: end-to-end Aerial Image Segmentation Via Deformable Point Network
Bibliographic record
Abstract
Aerial image Segmentation segmentation faces intrinsic foreground-background imbalance and background clutter distraction. To guide the segmentation model to learn more discriminative foreground ability and more invariant back-ground representation features, we design a Deformable Point Network (DPNet). It is an end-to-end segmentation network and consists of a multi-head deformable attention module that simultaneously considers foreground object information and background suppression. Specifically, we first employ a feature pyramid network to aggregate multiple-layer features to handle scale variants. And then, we further investigate deformable convolution to select some representative points for each layer and propose a differential module to implement it automatically instead of traditional dense fusion. Moreover, we incorporate the multi-head mechanism in the feature fusion to focus on the key contents from different representation regions. Experimental results on the representative iSAID, Vaihingen, and Postdam datasets demonstrate that our DPNet achieves competitive performance. Also, the multiple-head deformable attention facilitates the network convergence significantly.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
