- To use other algorithms of text detection and recognition, please set arguments: `--det-config`, `--det-ckpt`, `--recog-config`, `--recog-ckpt`.
- To use batch mode for text recognition, please set arguments: `--batch-mode`, `--batch-size`.

### Text Detection Image Demo
### Text Detection Single Image Demo
We provide a demo script to test a [single image](/demo/demo_text_det.jpg) for text detection with a single GPU.

### Text Detection Multiple Image Demo
We provide a demo script to test multi-images in batch mode for text detection with a single GPU.
*Text Detection Model Preparation:*
The pre-trained text detection model can be downloaded from [model zoo](https://mmocr.readthedocs.io/en/latest/modelzoo.html).
Take [PANet](/configs/textdet/panet/panet_r18_fpem_ffm_600e_icdar2015.py) as an example:
```shell
python demo/batch_image_demo.py ${CONFIG_FILE} ${CHECKPOINT_FILE} ${SAVE_PATH} --images ${IMAGE1} ${IMAGE2} [--imshow] [--device ${GPU_ID}]
```
Example:
```shell
python demo/batch_image_demo.py configs/textdet/panet/panet_r18_fpem_ffm_600e_icdar2015.py https://download.openmmlab.com/mmocr/textdet/panet/panet_r18_fpem_ffm_sbn_600e_icdar2015_20210219-42dbe46a.pth save_results --images demo/demo_text_det.jpg demo/demo_text_det.jpg
```
The predicted result will be saved in folder `save_results`.
### Text Detection Webcam Demo
We also provide live demos from a webcam as in [mmdetection](https://github.com/open-mmlab/mmdetection/blob/a616886bf1e8de325e6906b8c76b6a4924ef5520/docs/1_exist_data_model.md).
