Training

  1. Execute script init.sh(init.bat on Windows) to initialize project.
  2. Download pretrained model from here into model folder.
  3. Download dataset from google drive or baidu yun. This dataset is already prepared by @eragonruan to fit CTPN.
  4. Unzip the dataset downloaded to 'VOCdevkit' folder, and set both default.root_path and default.dataset_path in rcnn/config.py to '<somewhere>/VOCdevkit/VOC2007'. You can also change other hyperparams in rcnn/config.py.
  5. Run python train_ctpn.py to train. Run python train_ctpn.py --gpus '0' --rpn_lr 0.01 --no_flip 0 to train model on gpu 0 with learning rate 0.01 and with flip data augmentation.

Testing

Use python demo_ctpn.py --image "<your_image_path>" --prefix model/rpn1 --epoch 8 to test.
