Turning a CLIP Model into a Scene Text Detector

This repository is build upon mmocr 0.4.0.

NightTime-ArT Dataset

NightTime-ArT dataset, collected from ArT, can be downloaded from here.

Usage

Environment

The code is based on mmocr. Please first install the mmcv-full and mmocr following the official guidelines (mmocr).

Dataset

Pre-trained CLIP Models

model = dict(
    pretrained='xxx/ocrclip/pretrained/RN50.pt',
    )

Pretraining & Training & Evaluation

To pretrain the TCM model on SynthText/Synth150k, please configure the corresponding dataset path, then run:

bash dist_train.sh configs/textdet/xxnet/xxx.py 8

To finetune the TCM model based on pretrained model, please configure the load_from to the pretrained checkpoint path, then run:

bash dist_train.sh configs/textdet/xxnet/xxx.py 8

To evaluate the performance with checkpoint, run:

bash dist_test.sh configs/textdet/xxnet/xxx.py /path/to/checkpoint 1 --eval hmean-iou
