Document_Image_Dewarping

The code for "Foreground and Text-lines Aware Document Image Rectification", ICCV, 2023.

Training Dataset

We use the Doc3D dataset for training. You can download the dataset on DewarpNet or doc3D-dataset.

Evaluation Dataset

We evaluate on two datasets DocUNet Benchmark and DIR300.

Inference

Please download the pre-trained model from Google Drive or Baidu Cloud. Then execute:

python predict.py --model_path /MODEL/PATH --img_path /BENCHMARK/DIR --save_path /SAVE/PATH

Evaluation

We follow the evaluation environment and code in DocUNet and DocGeoNet.

For CER and ED metrics evaluation:

Tesseract==5.0.1.20220118 (Windows)
pytesseract==0.3.8

The dewarped images can be downloaded from Google Drive or Baidu Cloud.

Acknowledgement

Our methods and codes are inspired by many existing works, to which we would like to express special thanks to:
