Efficient Extraction Program for Academic Formulas
The formula recognition module based on UniMERNet technology supports three modes of operation:
- Batch processing mode:Execute after putting multiple PDFs into the same directory:
python pdf_extract.py -pdf . /paper_files/ -formula-only - LaTeX output:Results are automatically stored in standard LaTeX format and can be inserted directly into editors such as Overleaf.
- Visual calibration:Add the -render parameter to generate a rendered image and check the recognition results with outputs/Formula_Render/.
Advanced Tips:Complex formulas can be adjusted in configs/formula.yaml when encountered:
resolution: 600dpi # Enhanced input image quality
confidence_threshold: 0.85 # Filtering for Low Quality Identification
