Pytorch re-implementation of Paper: SwinTextSpotter: Scene Text Spotting via Better Synergy between Text Detection and Text Recognition (CVPR 2022)

SwinTextSpotter

This is the pytorch implementation of Paper: SwinTextSpotter: Scene Text Spotting via Better Synergy between Text Detection and Text Recognition (CVPR 2022). The paper is available at this link.

• We use the models pre-trained on ImageNet. The ImageNet pre-trained SwinTransformer backbone is obtained from SwinT_detectron2.

3. Pretrain SWINTS (e.g., with Swin-Transformer backbone)

python projects/SWINTS/train_net.py \
  --num-gpus 8 \
  --config-file projects/SWINTS/configs/SWINTS-swin-pretrain.yaml

4. Fine-tune model on the mixed real dataset

python projects/SWINTS/train_net.py \
  --num-gpus 8 \
  --config-file projects/SWINTS/configs/SWINTS-swin-mixtrain.yaml

5. Fine-tune model

python projects/SWINTS/train_net.py \
  --num-gpus 8 \
  --config-file projects/SWINTS/configs/SWINTS-swin-finetune-totaltext.yaml

6. Evaluate SWINTS (e.g., with Swin-Transformer backbone)

python projects/SWINTS/train_net.py \
  --config-file projects/SWINTS/configs/SWINTS-swin-finetune-totaltext.yaml \
  --eval-only MODEL.WEIGHTS ./output/model_final.pth

7. Visualize the detection and recognition results (e.g., with ResNet50 backbone)

python demo/demo.py \
  --config-file projects/SWINTS/configs/SWINTS-swin-finetune-totaltext.yaml \
  --input input1.jpg \
  --output ./output \
  --confidence-threshold 0.4 \
  --opts MODEL.WEIGHTS ./output/model_final.pth
