Assemble layout data
Collect scanned pages or PDFs with region-level annotations (bounding boxes and class labels) and include noisy scans and multi-column layouts.
Analyse document layout. Inspect predicted regions.
Document layout analysis segments pages into regions such as headings, paragraphs, tables and figures, and maps text blocks to structural labels. Real layouts require image or PDF parsing, bounding-box annotations, spatial features and robustness to noise from scans or multi-column formats.

Document layout analysis segments pages into regions such as headings, paragraphs, tables and figures, and maps text blocks to structural labels. Real layouts require image or PDF parsing, bounding-box annotations, spatial features and robustness to noise from scans or multi-column formats.
A proposed application: pre-processing scanned policy or contract pages to detect and route tables, signatures and clauses to downstream extractors. The supplied starter does not implement this and a human reviewer must validate automated routing in production.
Collect scanned pages or PDFs with region-level annotations (bounding boxes and class labels) and include noisy scans and multi-column layouts.
Start with an image-based detector (e.g. Faster R-CNN or U-Net on rendered page images) and include spatial features from text runs if OCR is available.
Use mAP for bounding boxes and per-class precision/recall; inspect failure cases such as overlapping regions and small tables.
Package detection and OCR in a pipeline, add latency and drift monitoring, and include a human-in-the-loop correction UI.
The supplied starter performs a simple text classification pipeline: it splits six short sentences and binary labels, fits a TF-IDF vectoriser plus LogisticRegression, prints a classification report and a single sample prediction. It contains no image/PDF parsing, no bounding boxes, and no layout detector.
model = Pipeline(
steps=[
("tfidf", TfidfVectorizer(ngram_range=(1, 2), min_df=1)),
("classifier", LogisticRegression(max_iter=1000)),
]
)
model.fit(X_train, y_train)The code is a text-level binary classifier on six hand-written sentences and does not use any document images, page-layout features, OCR text with positions, or region-level labels required for layout analysis.
Proposed extension: Detect layout regions (title, paragraph, table, figure, signature) on page images, then route detected tables and signatures to specialised extractors and a human-review queue when confidence is low.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
