  • Extensible
    Tesseract can be integrated with other tools and frameworks, such as image pre-processing libraries, to enhance its functionality and improve OCR results.

Possible disadvantages of Tesseract

  • Complex Setup
    Setting up Tesseract can be complex for beginners. It may require additional dependencies and configuration to perform optimally.
  • Performance
    Tesseract is not the fastest OCR engine available. For applications requiring real-time processing, its performance may be a bottleneck.
  • Image Quality Dependency
    Tesseract's accuracy heavily depends on the quality of the input image. Low-quality images or those with significant noise can lead to poor OCR results.
  • Limited Handwriting Recognition
    Tesseract primarily excels at printed text recognition and offers limited capabilities for handwritten text.
  • Resource Intensive
    Running Tesseract requires significant computational resources, which might be a limitation for mobile or low-power devices.
