# Formula recognition

PP-FormulaNet_plus-M and PP-DocLayout_plus-L are PaddlePaddle models (Apache-2.0).
ONNX exports: RapidAI/RapidDoc v1.0.0, Apache-2.0.

Preprocessing/token decoding follows the model interface documented in:
https://github.com/RapidAI/RapidDoc/tree/main/rapid_doc/model/formula/rapid_formula_self
https://github.com/RapidAI/RapidDoc/tree/main/rapid_doc/model/layout/rapid_layout_self

The C# implementation performs local detection followed by recognition of each
formula crop. Model URLs, exact sizes and SHA-256 are pinned in FormulaClient.cs.
No model weights or Python environment are bundled with the application.
