• 2024-04-26 Added Auto Recognition (supports three modes) feature to solve the issue of manually clicking recognition button in long-term, multiple recognition scenarios
• Added Auto Recognition (math formula recognition only) feature
• Added text-only recognition function and button
• Application icon no longer shows in dock after launch
• Fixed program freezing issue during long recognition processes
• Updated OCR recognition model to enhance handwritten math formula recognition
• Added mixed recognition for math formulas and text documents

• Test Results
• Menu Bar Application Interface

• Clone Repository

git clone https://github.com/horennel/LaTex-OCR_for_macOS.git

• Install Dependencies

pip3 install -r requirements.txt

• Package Application

python3 setup.py py2app -A

• Move the generated MyLatexOCR.app from the dist folder to your Applications folder

• Launch
  • Start MyLatexOCR, you'll see the application icon in the menu bar
• Screenshot
  • Use any screenshot tool (e.g., Snipaste) to capture and copy to clipboard
• Recognition
  • Math Formula Only
    • Click Formula OCR button
    • You'll receive a notification upon successful recognition
  • Mixed Math Formula and Text
    • Click Mixed OCR button
    • You'll receive a notification upon successful recognition
  • Text Only
    • Click Text OCR button
    • You'll receive a notification upon successful recognition
  • Notifications can be disabled in system settings
  • After receiving notification, you can paste the LaTeX formula and text anywhere
• Auto Recognition (supports Math Formula Mode, Mixed Mode, Text-Only Mode)
  • Enable/Disable Auto Recognition
    • Click Auto On/Off button to toggle auto recognition
    • Dark menu bar icon indicates auto recognition is enabled
    • Light menu bar icon indicates auto recognition is disabled
  • Usage
    • After enabling auto recognition (defaults to Math Formula Mode), click the corresponding mode button
    • Selected mode button becomes unclickable with a √ prefix
    • No further clicks needed, program automatically recognizes clipboard images
  • Important Notes ⚠️
    • Program automatically processes clipboard images but cannot determine if recognition is needed
    • Copying unneeded images with auto recognition enabled wastes system resources
    • Recommended to enable auto recognition only when continuous recognition is needed

• First launch will download models and configuration files, causing longer initial startup time
• Model and config files are stored in ～/.cnstd, ~/.cnocr, and ~/.pix2text
• Application depends on Python environment used during packaging. Repackaging needed if environment changes
