PaddlePaddle

Extract Formula (PaddleX)

Reads a cropped mathematical formula Image and emits its LaTeX source as a String via the PP-FormulaNet recognition head. Blank or unreadable crops return an empty String. One formula per frame, not a full page.

Extract Text (PaddleOCR)

Runs PaddleOCR (PP-OCRv5) detection and recognition over each Image, emitting either a joined String transcript or per-line regions with Polygon or Rectangle bounds and optional confidence. Optional orientation and unwarping.

Detect Document Layout (PP DocLayout)

Detects layout regions on each page Image with PP-DocLayout (PaddleX) and emits one detection per region as geometry-only [Rectangle] or [BoundingBox] carrying the model's 23-category layout class id and confidence, fixed at deploy by the consumer.

Extract Text (PaddleOCR VL)

PaddleOCR-VL document parsing. Each Image is parsed on the selected device with layout detection and vision-language recognition, emitting a joined String transcript or per-block regions with boxes. SOTA parser (PaddleOCR-VL-1.6, 0.9B); CUDA GPU required.
