Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Add unbiased SDF-to-density transform (scale SDF by angle to normal) without geometry priors (ablation) | NeuS · DTU | Chamfer distance (mean): 0.84 -> 0.71 | Helped |
| Add MVS geometry priors (zero-level-set supervision from CasMVSNet points) to NeuS-style rendering (ablation) | NeuS · DTU | Chamfer distance (mean): 0.84 -> 0.65 | Helped |
| Combine unbiased rendering with MVS geometry priors (full model) (ablation) | NeuS · DTU | Chamfer distance (mean): 0.84 -> 0.60 | Helped |
| Unbiased rendering with no geometry priors vs NeuralWarp | NeuS · DTU | Chamfer distance (mean): 0.71 vs 0.68 | No clear effect |
| Full method vs NeuS and VolSDF on view synthesis | NeuS · DTU | PSNR (mean): 31.97 -> 32.24 | Helped |
