## Model Zoo

| Source Dataset | Model | Epoch | File | Size |
|---------------|-------|-------|------|------|
| CTW-1500 | textgraph_vgg | 2964 | `textgraph_vgg_2964.pth` | ~147 MB |

## Details

- **CTW-1500** is a large-scale dataset for curved/scene text detection with 1,000 training images and 500 test images.
- This checkpoint was trained for **2,964 epochs** on CTW-1500, then used as initialization for LATeD fine-tuning.
- The pretrained model captures general text detection features: TR/TCL segmentation maps, sin/cos geometry prediction, and bounding box regression.
- Transferring CTW-1500 → LATeD accelerates convergence on the low-light domain.

## Usage

In `configs/train_LATeD.yaml`:

```yaml
model:
  pretrained_weight: ./checkpoints/pretrained/textgraph_vgg_2964.pth
```

## Download

Place the checkpoint file in this directory. The file should be named:
