Extracting a mathematical formula involves performing a two-stage processing flow:
Phase 1: Element Positioning
utilization--mode mathParameter startup formula recognition:python ocr_stage1.py --input math.pdf --mode math --output temp/
The program will:
1. Detecting formula regions through the MathPix API
2. Save the formula coordinates and crop image to the temp directory
Phase 2: Semantic Transformation
Parsing intermediate results generates structured output:python ocr_stage2.py --input temp/ --output final/ --format json
The output will contain:
1. The original LaTeX code (e.g.frac{x}{y^2})
2. Natural language descriptions (e.g., "Fractional equation with x in the numerator and y squared in the denominator")
3. Information on the location of formulas on the page
