Reconstruction Loss
Point-DMAE begins by generating point patches and calculating their density. High-density regions are selectively masked, then processed by a dual-branch Transformer (encoder/decoder) to reconstruct the masked points, learning robust features.
Performance & Impact
The research demonstrates that Point-DMAE significantly outperforms existing MAE-based methods in 3D object classification and achieves competitive results across various tasks, validating its innovative approach to point cloud representation learning.

Peak Classification Accuracy Increase over Point-MAE
Point-DMAE significantly outperforms baseline Point-MAE across various 3D object classification tasks on ScanObjectNN, demonstrating the effectiveness of density-directed masking.
| Metric | Point-MAE | Point-DMAE |
|---|---|---|
| ScanObjectNN OBJ-BG Accuracy | 90.02% | 94.15% |
| ScanObjectNN OBJ-ONLY Accuracy | 88.29% | 93.46% |
| ScanObjectNN PB-T50-RS Accuracy | 85.18% | 89.35% |
| ModelNet40 w/o Vote Accuracy | 93.2% | 93.4% |
| Part Segmentation mIoUc | 84.2% | 84.8% |
Point-DMAE consistently surpasses Point-MAE in accuracy across multiple benchmarks, showcasing the benefits of its density-directed and dual-branch approach.
Masking Strategy & Architecture Impact
Ablation studies meticulously examine the individual contributions of Point-DMAE's core components: the density-directed masking strategy and the dual-branch Transformer architecture.
| Masking Type | Architecture | OBJ-BG (%) | OBJ-ONLY (%) | PB-T50-RS (%) |
|---|---|---|---|---|
| Random | Global Only | 93.11 | 91.74 | 89.10 |
| Random | Local Only | 92.42 | 92.08 | 88.90 |
| Random | Dual-Branch | 93.46 | 92.77 | 89.31 |
| Density-directed | Global Only | 93.80 | 92.60 | 89.04 |
| Density-directed | Local Only | 92.94 | 92.77 | 89.21 |
| Density-directed | Dual-Branch | 94.15 | 93.46 | 89.35 |
Ablation studies confirm the superiority of density-directed masking and the dual-branch architecture in capturing both high-level and fine-grained features. Density-directed masking consistently outperforms random masking, highlighting its importance for point cloud data due to uneven information distribution. The dual-branch approach also demonstrates superior performance by effectively learning both global and local features.
