| # hires1920 Depth Backup |
|
|
| Cold backup of **high-resolution (1920×1088) monocular depth pseudo-labels** with their |
| source photographs — the high-res counterpart of the pipeline behind |
| [`androidli/photo-depth-pseudo-labels`](https://huggingface.co/datasets/androidli/photo-depth-pseudo-labels). |
| Published as-is so the exact arrays used in our experiments stay reproducible. |
|
|
| Depth labels were produced with a **Depth-Anything-V2** teacher over public photo-library |
| images (Wikimedia Commons / iNaturalist / Openverse / Pexels / Pixabay / Burst and |
| other collections). |

|
| ## Layout |
|
|
| | Path | Content | |
| |---|---| |
| | `hires1920/cold/` | 148 shards, ~145 GB — current generation (`shard_s0_*.npz`) | |
| | `hires1920/oldpool/` | 61 shards, ~60 GB — older generation kept for lineage (`shard_old_s0_*.npz`) | |
| | `quota_test.bin` | 1 MB LFS upload-test artifact — ignore | |
|
|
| Each ~1 GB `.npz` shard is self-contained and holds ~512 samples as object arrays: |
|
|
| | Array | Content | |
| |---|---| |
| | `id` | sample identifier | |
| | `box` | bounding box / crop metadata | |
| | `rgb_jpg` | the source photograph, JPEG bytes | |
| | `gt_b2` | depth ground truth, **blosc2-compressed float16**, 1088×1920 | |
|
|
| ```python |
| import io, blosc2, numpy as np |
| from PIL import Image |
| z = np.load("hires1920/cold/shard_s0_00030.npz", allow_pickle=True) |
| raw = z["rgb_jpg"][0] # JPEG bytes (object array) |
| rgb = np.asarray(Image.open(io.BytesIO(bytes(raw))).convert("RGB")) |
| gt = blosc2.decompress2(z["gt_b2"][0].tobytes()) |
| depth = np.frombuffer(gt, dtype=np.float16).reshape(1088, 1920) |
| ``` |
|
|
| ## Depth semantics |
|
|
| Depth-Anything raw convention: **larger value = farther, `0` = sky / invalid** (≈30% of |
| pixels can be 0). Relative depth only — no metric scale, no intrinsics. |
|
|
| ## Licensing |
|
|
| No formal license is attached to this repository — it is published **as-is, for research |
| reproducibility only**. What the components are, so you can judge reuse yourself: |
|
|
| - **Depth arrays (`gt_b2`)** — our own model outputs, produced with a Depth-Anything-V2 |
| teacher over the photos below. |
| - **Photographs (`rgb_jpg`)** — third-party images kept **as collected**, mixed licenses |
| per source, a large share collected without a recorded license. **Do not assume every |
| photo is redistributable.** Per-sample provenance for the overlapping pipeline is in |
| `photo-depth-pseudo-labels/metadata/` (`index.csv`, `attribution.csv`); check there |
| before re-sharing any bundled image. |
|
|
| If you want to reuse this data beyond research, or you are a rights holder and want |
| samples removed, **open an issue on this repo** and we'll sort it out promptly. |
|
|
| ## Limitations |
|
|
| - `oldpool/` is a legacy generation: expect format/quality drift vs `cold/`. |
| - `shard_s0_*` naming is an internal convention, not a stable contract; treat shard |
| indices as opaque. |
| - No per-sample `license` column inside the shards — join against the photo-depth |
| metadata for licensing detail. |
