# CM-EVS curator code (reviewer reference)

This directory mirrors the curator source code from the (anonymized) GitHub release. It's included here so reviewers can cross-reference implementation details against the paper without needing two URLs.

## Layout

```

├── core/                       (curator core modules — coordinate, ERP projection / warping,
│                                tangent extraction, depth fusion, …)
├── scripts/                    (per-step CLI scripts — build_candidates, select_views,

│                                audit_quality, run_tiny.sh, …)
├── pipelines/                  (per-source end-to-end runners — Blender, HM3D,

```

## Quick start

```bash
conda env create -f environment.yml
conda activate cmevs

# tiny smoke test (uses examples/tiny_blender_scene/)
bash scripts/run_tiny.sh

# real run:
python pipelines/run_blend_pipeline.py    --config configs/blender_indoor.yaml
python pipelines/run_hm3d_pipeline.py     --config configs/hm3d.yaml
python pipelines/run_ply_pipeline.py      --config configs/scannetpp.yaml
```

## Mapping paper sections → code

| Paper section | Code |
| --- | --- |
| §3.1 Setup (candidates, budget, coverage) | `scripts/build_candidates.py`, `core/coordinate.py` |
| §3.2 Conflict-aware warping oracle | `core/erp_warp.py`, `scripts/selection_metrics.py` |
| §3.3 Pipeline three phases | `pipelines/run_blend_pipeline.py`, `run_hm3d_pipeline.py`, `run_ply_pipeline.py` |
| §3.4 Adapters (Table 2) | `pipelines/run_*_pipeline.py` per source |
| Algorithm 1 (greedy) | `scripts/select_views.py` |
| §3.6 Adaptive frame budgets (early stop) | `scripts/select_views.py` (`stop_gain`, `stop_score`, `stop_delta` flags) |
| §4.1 Output schema | `core/coordinate.py`, `core/erp_projection.py`, `metadata_examples/*.schema.json` |
| §4.8 per-frame quality | `scripts/audit_quality.py` |
| §5.1 Fixed-budget coverage | `scripts/evaluate_coverage.py` |
| §5.2 Warping oracle vs pre-render-all | `scripts/evaluate_oracle_gap.py` |
| §F.2 50-frame audit | `scripts/audit_quality.py` (extended audit mode) |

## Reproducibility

All curator parameters that affect paper numbers are in `configs/*.yaml`. The reviewer can:

1. Inspect each YAML to confirm parameter values match the paper.
2. Run a smoke test against `examples/tiny_blender_scene/` to confirm the code executes end-to-end.
3. Reproduce the full pipeline against actual data (Blender indoor frames are in `../blender_indoor/`; HM3D / ScanNet++ / outdoor data must be obtained from upstream).
