This is the training dataset used in the paper **Thinking In Boxes: 3D Editing in Real Images Made Easy**

Thinking-In-Boxes is an Image-to-Image Generative model for Geometric Image Editing. 
This dataset consists of images of 1-2 object scenes placed on a floor and rendered from two viewpoints. 
In addition, it includes our scene representation where objects as represented as 3D Coloured Boxes placed on a shaded floor, which disambiguates object and camera transformations.

## Dataset Structure

This dataset contains three independent subsets, each stored as WebDataset `.tar` shards:

| Subset | Folder | Approx. size | Description |
|---|---|---|---|
| 100K-Syn | `data/100K-Syn/` | 100,000 scenes | Synthetic 2-object scenes used in Stage-1 finetuning |
| 10K-Objectron | `data/10K-Objectron/` | 10,000 scenes | Real-world Objectron-derived scenes used in Stage-2 finetuning |
| 10K-Syn | `data/10K-Syn/` | 10,000 scenes | Synthetic 2-object scenes used in Stage-2 finetuning |

Each "scene" (sample) contains 4 files:

- `bbox_0.png`, `bbox_1.png` — scene representations for source and target configurations.
- `rgb_0.png`, `rgb_1.png` — RGB renders representing source and target configurations.

**Note**: The *.png files for the 100K-Syn and 10K-Syn subsets are in 512x512 resolution, and 1440x1920 resolution for the 10K-Objectron subset.

## Usage

Each subset is loaded independently via `data_dir` (all share the same `train` split label — `data_dir` is what distinguishes them, not `split`):

```python
from datasets import load_dataset

ds_100K_Syn = load_dataset("pradhaansbhat/Thinking-In-Boxes", data_dir="data/100K-Syn", split="train")
ds_10K_Objectron = load_dataset("pradhaansbhat/Thinking-In-Boxes", data_dir="data/10K-Objectron", split="train")

print(ds_100K_Syn[0].keys())
# dict_keys(['bbox_0.png', 'bbox_1.png', 'rgb_0.png', 'rgb_1.png', '__key__', '__url__'])
```

Alternatively, using the named configs defined above:

```python
from datasets import load_dataset

ds_100K_Syn = load_dataset("pradhaansbhat/Thinking-In-Boxes", "100K-Syn", split="train")
ds_10K_Objectron = load_dataset("pradhaansbhat/Thinking-In-Boxes", "10K-Objectron", split="train")
ds_10K_Syn = load_dataset("pradhaansbhat/Thinking-In-Boxes", "10K-Objectron", split="train")
```

### Merging subsets for training

```python
from datasets import concatenate_datasets
from torch.utils.data import DataLoader

merged = concatenate_datasets([ds_10K_Objectron, ds_10K_Syn])  # e.g. combine the two 10K sets
loader = DataLoader(merged, batch_size=2, shuffle=True, num_workers=8)
```

**Note**: `__key__` values (e.g. `scene_000000`) are unique within each subset but **not** guaranteed unique across subsets after merging. This has no effect on training but is worth knowing if you rely on `__key__` for deduplication or lookups across merged data.
