💻 Usage Examples

🔍 Basic Usage

You can quickly experience the functionality with a single command:

paddleocr text_recognition \
    --model_name arabic_PP-OCRv3_mobile_rec \
    -i https://cdn-uploads.huggingface.co/production/uploads/681c1ecd9539bdde5ae1733c/EPkFpN_xkKTh1URMOsjE6.png

You can also integrate the model inference of the text recognition module into your project. Before running the following code, please download the sample image to your local machine.

from paddleocr import TextRecognition
model = TextRecognition(model_name="arabic_PP-OCRv3_mobile_rec")
output = model.predict(input="EPkFpN_xkKTh1URMOsjE6.png", batch_size=1)
for res in output:
    res.print()
    res.save_to_img(save_path="./output/")
    res.save_to_json(save_path="./output/res.json")

After running, the obtained result is as follows:

{'res': {'input_path': '/root/.paddlex/predict_input/EPkFpN_xkKTh1URMOsjE6.png', 'page_index': None, 'rec_text': 'ددعتم يبرع صن رابتخا ةلاح', 'rec_score': 0.9411801695823669}}

For details about usage command and descriptions of parameters, please refer to the Document.

⚙️ Advanced Usage

The ability of a single model is limited. But the pipeline consists of several models can provide more capacity to resolve difficult problems in real-world scenarios.

🌟 PP-OCRv3

The general OCR pipeline is used to solve text recognition tasks by extracting text information from images and outputting it in string format. And there are 5 modules in the pipeline:

• Document Image Orientation Classification Module (Optional)
• Text Image Unwarping Module (Optional)
• Text Line Orientation Classification Module (Optional)
• Text Detection Module
• Text Recognition Module

Run a single command to quickly experience the OCR pipeline:

paddleocr ocr -i https://cdn-uploads.huggingface.co/production/uploads/681c1ecd9539bdde5ae1733c/Z1WF0PAh9lBnXZdOYE9QL.png \
    --text_recognition_model_name arabic_PP-OCRv3_mobile_rec \
    --use_doc_orientation_classify False \
    --use_doc_unwarping False \
    --use_textline_orientation True \
    --save_path ./output \
    --device gpu:0 

Results are printed to the terminal:

{'res': {'input_path': '/root/.paddlex/predict_input/Z1WF0PAh9lBnXZdOYE9QL.png', 'page_index': None, 'model_settings': {'use_doc_preprocessor': True, 'use_textline_orientation': True}, 'doc_preprocessor_res': {'input_path': None, 'page_index': None, 'model_settings': {'use_doc_orientation_classify': False, 'use_doc_unwarping': False}, 'angle': -1}, 'dt_polys': array([[[  6,   5],
        ...,
        [  6,  38]],

       [[199,  32],
        ...,
        [200,  68]]], dtype=int16), 'text_det_params': {'limit_side_len': 64, 'limit_type': 'min', 'thresh': 0.3, 'max_side_limit': 4000, 'box_thresh': 0.6, 'unclip_ratio': 1.5}, 'text_type': 'general', 'textline_orientation_angles': array([0, 0]), 'text_rec_score_thresh': 0.0, 'rec_texts': ['ددعتم يبرع صن رابتخاةلاح', 'رطسألا'], 'rec_scores': array([0.98472452, 0.99996692]), 'rec_polys': array([[[  6,   5],
        ...,
        [  6,  38]],

       [[199,  32],
        ...,
        [200,  68]]], dtype=int16), 'rec_boxes': array([[  6, ...,  38],
       [199, ...,  68]], dtype=int16)}}

The command-line method is for quick experience. For project integration, also only a few codes are needed as well:

from paddleocr import PaddleOCR  

ocr = PaddleOCR(
    text_recognition_model_name="arabic_PP-OCRv3_mobile_rec",
    use_doc_orientation_classify=False, # Use use_doc_orientation_classify to enable/disable document orientation classification model
    use_doc_unwarping=False, # Use use_doc_unwarping to enable/disable document unwarping module
    use_textline_orientation=True, # Use use_textline_orientation to enable/disable textline orientation classification model
    device="gpu:0", # Use device to specify GPU for model inference
)
result = ocr.predict("https://cdn-uploads.huggingface.co/production/uploads/681c1ecd9539bdde5ae1733c/Z1WF0PAh9lBnXZdOYE9QL.png")  
for res in result:  
    res.print()  
    res.save_to_img("output")  
    res.save_to_json("output")

The default model used in pipeline is PP-OCRv5_server_rec, so it is needed that specifing to arabic_PP-OCRv3_mobile_rec by argument text_recognition_model_name. And you can also use the local model file by argument text_recognition_model_dir. For details about usage command and descriptions of parameters, please refer to the Document.

✨ Features

arabic_PP-OCRv3_mobile_rec is a text line recognition model within the PP-OCRv3_rec series, developed by the PaddleOCR team. It is an Arabic-alphabet-specific model trained based on PP-OCRv3_mobile_rec, supporting Arabic alphabet recognition. The key accuracy metrics are as follow:

Note: If any character (including punctuation) in a line was incorrect, the entire line was marked as wrong. This ensures higher accuracy in practical applications.
