Image Extraction Fixtures

PNG, JPEG, TIFF, and scan-style PDF fixtures for OCR, document-photo capture, scan preprocessing, and image-based extraction workflows.

Why This Workflow Matters

  • Mix clean scans, noisy OCR inputs, mobile-photo captures, and TIFF archival sources in one workflow.
  • Use image and PDF fixtures together to compare scan ingestion against fixed-layout document extraction.
  • Anchored to a downloadable pack so teams can seed OCR and preprocessing suites quickly.

Fixture Matrices

PNG OCR Fixture Matrix

Pick PNG fixtures for clean receipt scans, grayscale OCR preprocessing, and image-based extraction smoke tests.

JPEG Document Capture Matrix

Choose JPEG fixtures for mobile document photos, compressed receipt captures, and OCR workflows that start from camera images.

TIFF Scan Fixture Matrix
