| # CamEdit50K: Focal Plane Subset |
|
|
| This dataset is part of the **CamEdit** project — a diffusion-based framework for continuous camera parameter control in photorealistic image editing. This subset focuses on **focal plane** manipulation, providing paired data for training models that can re-render images at different focal planes via text instructions. |

|
|
| ## Dataset Structure |
|
|
| ### Files |
|
|
| Each shard consists of a `.tar` archive containing the images and a `.parquet` file containing the metadata: |
|
|
| ``` |
| CamEdit_Focal_001.tar # images (input/ and gt/ subfolders) |
| CamEdit_Focal_001.parquet # metadata for this shard |
| ... |
| CamEdit_Focal_011.tar |
| CamEdit_Focal_011.parquet |
| CamEditckpt_@_.tar # pretrained LoRA checkpoints (AP / FP / SP) |
| ``` |
|
|
| ### Image Folder Layout |
|
|
| Each tar archive extracts to: |
|
|
| ``` |
| CamEdit_Focal_XXX/ |
| ├── input/ # original images |
| │ ├── 0000049.jpg |
| │ └── ... |
| └── gt/ # ground-truth edited images |
| ├── 0000049-focal-0.3.jpg |
| └── ... |
| ``` |
|
|
| ### Parquet Schema |
|
|
| | Column | Type | Description | |
| |---|---|---| |
| | `index` | string | Unique sample ID | |
| | `original_image_path` | string | Relative path to the input image | |
| | `edited_image_path` | string | Relative path to the ground-truth edited image | |
| | `instruction` | string | Text instruction, e.g. *"Render the image with focal plane 0.3."* | |
| | `height` | int | Image height in pixels | |
| | `width` | int | Image width in pixels | |
| | `task` | string | Task type (`Focal Plane`); absent in shards 008–011 | |
| | `parameter` | string | Focal plane value (0–1) | |
|
|
| ### Per-Shard Statistics |
|
|
| | Shard | Input Images | Pairs | Size | |
| |---|---|---|---| |
| | Focal_001 | 1,942 | 3,000 | 3.75 GB | |
| | Focal_002 | 1,941 | 3,000 | 3.70 GB | |
| | Focal_003 | 1,935 | 3,000 | 3.72 GB | |
| | Focal_004 | 1,961 | 3,000 | 3.79 GB | |
| | Focal_005 | 1,940 | 3,000 | 3.72 GB | |
| | Focal_006 | 1,936 | 3,000 | 3.66 GB | |
| | Focal_007 | 1,626 | 2,620 | 2.87 GB | |
| | Focal_008 | 530 | 3,000 | 1.17 GB | |
| | Focal_009 | 1,668 | 3,000 | 1.27 GB | |
| | Focal_010 | 3,000 | 3,000 | 2.16 GB | |
| | Focal_011 | 1,083 | 1,083 | 0.81 GB | |
| |
| ### Checkpoints |
| |
| `CamEditckpt_@_.tar` contains pretrained LoRA weights and tokenizer embeddings for three camera parameter editing tasks: |
| |
| - **AP** — Aperture |
| - **FP** — Focal Plane |
| - **SP** — Shutter Speed |
| |
| Each subfolder includes: |
| - `pytorch_lora_weights.safetensors` |
| - `Embed_one/`, `Embed_two/`, `Embed_three/` (learned camera token embeddings) |
| - `tokenizer/`, `tokenizer_2/`, `tokenizer_3/` |
|
|
| ## Usage |
|
|
| ```python |
| import pandas as pd, tarfile |
| |
| # Read metadata |
| df = pd.read_parquet("CamEdit_Focal_001.parquet") |
| |
| # Extract images |
| with tarfile.open("CamEdit_Focal_001.tar") as tar: |
| tar.extractall(".") |
| |
| # Access a sample |
| row = df.iloc[0] |
| print(row.instruction) # "Render the image with focal plane 0.3." |
| print(row.original_image_path) # "CamEdit_Focal_001/input/0042680.jpg" |
| print(row.edited_image_path) # "CamEdit_Focal_001/gt/0042680-focal-0.3.jpg" |
| ``` |
