| # DeepFashion-Camera |
|
|
|  |
|
|
| Per-image camera parameter annotations for the **DeepFashion** dataset |
| (full-body fashion model photographs; 13,679 images), captioned by the [**Puffin-World**](https://github.com/KangLiao929/Puffin) model. More captioned datasets are provided in our [**Puffin-16M**](https://kangliao929.github.io/projects/puffin-16m/) website. |
|
|
| The collage above visualizes the camera maps on sample images — each |
| pair shows the **up field** (green arrows: the projected gravity-up direction) |
| and the **latitude field** (colored contours: angle above/below the horizon). |
|
|
| ## Format |
|
|
| One `.tar` per shard (`deepfashion_0000.tar` … ), each containing one `.json` |
| per image whose name matches the source image stem. Only the main person |
| photograph (the `image` field) is captioned; auxiliary pose / cloth views are |
| excluded. |
|
|
| Each JSON holds the predicted monocular camera parameters: |
|
|
| | Field | Meaning | Unit | |
| |-------|---------|------| |
| | `roll` | camera roll | radians | |
| | `pitch` | camera pitch | radians | |
| | `vfov` | vertical field-of-view | radians | |
| | `k1` | radial distortion coefficient | – | |
| | `parse_ok` | whether the model output parsed within valid ranges | bool | |
|
|
| Example: |
|
|
| ```json |
| {"roll": 0.0123, "pitch": 0.0087, "vfov": 0.5691, "k1": 0.0000, "parse_ok": true} |
| ``` |
|
|
| ## Camera Parameter Distributions |
|
|
| Histograms of the predicted roll / pitch / vertical-FoV over the whole dataset |
| (proportion of valid samples per 10° bin; `parse_ok=False` excluded). |
|
|
|  |
|
|
| | split | roll μ / med / σ | pitch μ / med / σ | FoV μ / med / σ | |
| |-------|------------------|-------------------|-----------------| |
| | all (13,675) | 0.1° / 0.3° / 3.5° | 1.1° / 0.4° / 3.6° | 32.6° / 32.1° / 3.4° | |
|
|
| - **Roll** and **pitch** are both tightly centered near 0° (level, front-on |
| full-body shots). |
| - **FoV** is remarkably consistent (σ ≈ 3.4°, the tightest of our captioned sets) |
| — studio fashion photography frames the model with a near-constant focal length. |
|
|
| If you'd like a dataset with a more diverse and uniform distribution of camera parameters, please refer to our [Puffin-4M](https://huggingface.co/datasets/KangLiao/Puffin-4M) and [Puffin-16M](https://huggingface.co/datasets/KangLiao/Puffin-16M) datasets. |
|
|
| ### Dataset Download |
| You can download the entire dataset using the following command: |
| ```bash |
| hf download KangLiao/DeepFashion-Camera --repo-type dataset |
| ``` |
|
|
| ### Caption Pipeline |
| Beyond this captioned dataset, we also release **a complete captioning pipeline** for annotating camera parameters for arbitrary datasets, analyzing camera parameter distributions, and visualizing the corresponding camera maps. The pipeline is available in our [GitHub repository](https://github.com/KangLiao929/Puffin). |
