## Text Recognition Demo

### Text Recognition Image Demo We provide a demo script to test a [single demo image](/demo/demo_text_recog.jpg) for text recognition with a single GPU. *Text Recognition Model Preparation:* The pre-trained text recognition model can be downloaded from [model zoo](https://mmocr.readthedocs.io/en/latest/modelzoo.html). Take [SAR](/configs/textrecog/sar/sar_r31_parallel_decoder_academic.py) as an example: ```shell python demo/image_demo.py ${TEST_IMG} ${CONFIG_FILE} ${CHECKPOINT_FILE} ${SAVE_PATH} [--imshow] [--device ${GPU_ID}] ``` Example: ```shell python demo/image_demo.py demo/demo_text_recog.jpg configs/textrecog/sar/sar_r31_parallel_decoder_academic.py https://download.openmmlab.com/mmocr/textrecog/sar/sar_r31_parallel_decoder_academic-dba3a4a3.pth demo/demo_text_recog_pred.jpg ``` The predicted result will be saved as `demo/demo_text_recog_pred.jpg`. ### Text Recognition 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). ```shell python demo/webcam_demo.py \ ${CONFIG_FILE} \ ${CHECKPOINT_FILE} \ [--device ${GPU_ID}] \ [--camera-id ${CAMERA-ID}] \ [--score-thr ${SCORE_THR}] ``` Examples: ```shell python demo/webcam_demo.py \ configs/textrecog/sar/sar_r31_parallel_decoder_academic.py \ https://download.openmmlab.com/mmocr/textrecog/sar/sar_r31_parallel_decoder_academic-dba3a4a3.pth ``` ### Remarks 1. If `--imshow` is specified, the demo will also show the image with OpenCV. 2. The `image_demo.py` script only supports GPU and so the `--device` parameter cannot take cpu as an argument.
