Sample Results
Overview
PyTorch implementation for CRAFT text detector that effectively detect text area by exploring each character region and affinity between characters. The bounding box of texts are obtained by simply finding minimum bounding rectangles on binary map after thresholding character region and affinity scores.

Getting started
Install dependencies
Requirements
- PyTorch>=0.4.1
- torchvision>=0.2.1
- opencv-python>=3.4.2

pip install -r requirements.txt
Training
We are currently in the process of cleaning training code for disclosure.
Test instruction using pretrained model
- Download Trained Model on IC13,IC17
- Run with pretrained model
python test.py --trained_model=[weightfile] --test_folder=[folder path to test images]
The result image and socre maps will be saved to ./result by default.
Arguments
--trained_model: pretrained model--text_threshold: text confidence threshold--low_text: text low-bound score--link_threshold: link confidence threshold--canvas_size: max image size for inference--mag_ratio: image magnification ratio--show_time: show processing time--test_folder: folder path to input images
