Product Details

ViTLP is a visually guided generative text layout pre-trained model designed to improve the efficiency and accuracy of intelligent document processing. This model combines OCR text positioning and recognition capabilities to enable fast and accurate text detection and recognition on document images. The pre-trained version of the ViTLP model, ViTLP-medium (380M parameters), provides a balanced solution under the constraints of computing resources and pre-training data set size, which not only ensures the performance of the model, but also optimizes the inference speed and memory usage. ViTLP's inference speed is typically 5 to 10 seconds on an Nvidia 4090 for processing a page of document images, which is competitive with most OCR engines.

Main Features

1
• Native OCR text positioning and recognition: ViTLP can position and recognize text directly on document images.
2
• Pre-trained model ViTLP-medium: Provides a pre-trained model with 380M parameters, which can provide better performance under limited computing resources.
3
• Fast inference speed: On Nvidia 4090, ViTLP can process document images quickly, and the inference speed can complete the processing of a page of document images in 5 to 10 seconds.
4
• Huggingface platform support: The pre-trained weights of the ViTLP model can be found on the Huggingface platform, making it easy for users to download and use.
5
• Easy to integrate and use: With the provided code and instructions, users can easily integrate ViTLP into their own projects.
6
• Support batch decoding: Through the provided decode.sh script, users can decode batch document images.
7
• Suitable for intelligent document processing: ViTLP is particularly suitable for scenarios that require document image text detection and recognition, such as automated document processing, archive digitization, etc.

How to Use

1
1. Visit ViTLP’s GitHub page and clone the project locally.
2
2. To install the required dependencies, run `pip install -r requirements.txt`.
3
3. Clone the pre-trained ViTLP model weights to the specified directory, use `git clone https://huggingface.co/veason/ViTLP-medium ckpts/ViTLP-medium`.
4
4. Run the demo, use `python ocr.py` and upload the document image for testing.
5
5. View `decode.py` for detailed inference code, and you can run batch decoding through `bash decode.sh`.
6
6. If you need to fine-tune ViTLP, you can refer to the guide in the `./finetuning` directory.

Target Users

The target audience is enterprises and research institutions that require document image processing, especially those that require automated document processing and archive digitization. ViTLP's fast inference speed and high accuracy make it ideal for these scenarios.

Examples

Case 1: Use ViTLP to digitize historical documents and automatically extract text information in the documents.

Case 2: In the legal field, ViTLP is used to automatically process and extract information from a large number of case documents.

Case 3: In the financial industry, ViTLP is used to intelligently analyze contract documents and extract key terms.
