Image Equation Converter

The image equation converter analyzes an uploaded image containing mathematical notation and outputs a machine-readable formula; primary output is LaTeX, with optional MathML. It is designed for students digitizing homework, educators preparing material, and researchers collecting formulas from figures. The process emphasizes accurate symbol identification and preservation of layout semantics so the resulting code can be edited or embedded in documents and notebooks.
Under the hood, the tool performs preprocessing (noise reduction, contrast enhancement, deskew), detects symbol regions, classifies glyphs, and reconstructs the hierarchical structure of the expression. It then generates LaTeX code and, if requested, MathML or a JSON symbol map with per-symbol confidence. Results include a reproducible transcription for repeated inputs.
Common use cases include converting printed equations from textbooks, handwritten notes, whiteboard images, or research figures into editable math in papers and slides. The converter supports multi-line formulas, integrals, sums, matrices, and subscripts, with proper LaTeX syntax. It is valuable where manual transcription is time-consuming or error-prone.
Key differentiators include robust symbol-level recognition, structured output with confidence metrics, and optional multi-format exports. Users can integrate the tool into workflows, notebooks, or publishing pipelines to accelerate digitization, ensure consistency, and reduce manual retyping.
