Introduces RoDLA, a robustness benchmark for document layout analysis with 12 document perturbations at 3 severity levels across PubLayNet-P, DocLayNet-P and M6Doc-P, plus the mPE and mRD metrics and a robustness-enhanced DINO-style model with channel attention and average pooling.
Problem
Document layout analysis models are evaluated on clean documents, and their robustness to realistic document perturbations (scanning, photographing artifacts) is underexplored; existing degradation metrics depend on a chosen baseline model.
Approach
Build a hierarchical taxonomy of 12 realistic document perturbations in 5 groups with 3 severity levels, propose mPE (combining IQA scores and model degradation) and mRD to measure perturbation effect and model robustness independent of a single baseline, and propose RoDLA, which adds channel attention and dilated average pooling to a DINO-based encoder to suppress attention on perturbed tokens.
Key results
- RoDLA achieves mRD of 116.0 on PubLayNet-P with 70.0% P-Avg mAP and 96.0% clean mAP, versus 120.7 for the next best DINO-InternImage in mRD.
- On DocLayNet-P, RoDLA reaches 80.5% clean mAP, 65.6% P-Avg and mRD 135.7, versus SwinDocSegmenter at mRD 282.7.
- On M6Doc-P, RoDLA obtains 70.0% clean mAP, 61.7% P-Avg and mRD 147.6, the lowest among compared methods.

Surprising findings
- SwinDocSegmenter drops from 93.7% to 37.3% and 29.2% mAP under blur, showing large fragility of some DLA models.
- The multimodal LayoutLMv3 does not show better robustness than the unimodal DiT on PubLayNet-P.
Limitations
- Benchmark covers only vision-based single-modal DLA models in its evaluation scope
- No human-in-the-loop testing of robustness
- Degradation component of mRD still relies on a baseline model (Faster R-CNN) for mPE
