The GOT OCR2 0 Model

The GOT-OCR2_0 model, developed by the stepfun-ai team, represents a significant advancement in Optical Character Recognition (OCR) technology. This model is part of the broader movement towards OCR-2.0, which aims to enhance the capabilities of traditional OCR systems to meet modern demands for intelligent processing of various optical characters.

Overview of GOT OCR2 0

GOT-OCR2_0 is a unified end-to-end model designed to bridge the gap between traditional OCR systems (referred to as OCR-1.0) and the evolving needs for more sophisticated optical character processing. The model is built on a general OCR theory that encompasses a wide range of artificial optical signals, including plain text, mathematical formulas, tables, charts, and even geometric shapes. This versatility makes GOT-OCR2_0 suitable for various applications beyond simple text recognition.

Key Features

  • Unified Model: GOT-OCR2_0 integrates multiple OCR tasks into a single framework, allowing it to process diverse types of characters and formats.
  • Interactive OCR Capabilities: The model supports region-level recognition based on coordinates or colors, enhancing its usability in complex scenarios.
  • Dynamic Resolution and Multi-page Support: It adapts to ultra-high-resolution images and can handle multi-page documents efficiently, addressing common challenges faced in traditional OCR systems.
  • Output Flexibility: The model can generate results in various formats, including plain text and structured formats like LaTeX or Markdown, which are particularly useful for academic and technical applications.

Architecture

The architecture of GOT-OCR2_0 consists of two main components: an encoder and a decoder.

Encoder

  • High-Compression Design: The encoder is designed to compress input images into tokens efficiently. It has approximately 80 million parameters and can handle input sizes up to 1024x1024 pixels.
  • Token Generation: Each input image is transformed into tokens with dimensions of 256x1024, which facilitates subsequent processing by the decoder.

Decoder

  • Long Context Length: The decoder features around 500 million parameters and supports token lengths up to 8K. This capability is crucial for processing long documents or complex layouts that require extensive context for accurate recognition.
  • Training Strategy: The training process for GOT-OCR2_0 involves three stages:
  • Decoupled pre-training of the encoder.
  • Joint training of the encoder with a new decoder.
  • Post-training of the decoder to refine its performance.

Use Cases

  • Academic Research: Researchers can use it to digitize complex documents that include mathematical formulas, tables, and figures, converting them into editable formats.
  • Business Applications: Companies can automate data extraction from invoices, contracts, and reports by utilizing the model's ability to recognize structured data.
  • Creative Industries: Artists and designers can leverage the model for recognizing handwritten notes or sketches, facilitating easier digital archiving and manipulation.
  • Accessibility Tools: The model can assist visually impaired individuals by converting printed materials into spoken words or braille formats through integration with other technologies.
  • Historical Document Preservation: Libraries and archives can use GOT-OCR2_0 to digitize old manuscripts and books while preserving their original formatting.

Performance and Advantages

In various experiments conducted by the developers, GOT-OCR2_0 has demonstrated superior performance compared to traditional OCR models. Its ability to handle a wide range of character types and formats sets it apart as a leading solution in the OCR landscape.

Advantages

  • Versatility: Unlike conventional OCR systems that primarily focus on plain text, GOT-OCR2_0 can recognize diverse characters such as charts and geometric shapes.
