1. Which explanation matches locate text in an image?A. OCR predicts characters; domain checks can flag unlikely formats or missing fields.B. Structured extraction links recognized text to fields using position, layout, and semantic constraints.C. Review workflows should expose the image region, confidence, and competing interpretations.D. Text detection proposes regions where characters may appear before recognition.

2. Which explanation matches recognize and validate text?A. Text detection proposes regions where characters may appear before recognition.B. Structured extraction links recognized text to fields using position, layout, and semantic constraints.C. OCR predicts characters; domain checks can flag unlikely formats or missing fields.D. Review workflows should expose the image region, confidence, and competing interpretations.

3. Which explanation matches read a form as structured fields?A. Text detection proposes regions where characters may appear before recognition.B. Structured extraction links recognized text to fields using position, layout, and semantic constraints.C. OCR predicts characters; domain checks can flag unlikely formats or missing fields.D. Review workflows should expose the image region, confidence, and competing interpretations.

4. For recognize and validate text, which result or action fits this practical case: The reader extracts a postal code from a blurred form.A. Validate a five-digit code against its expected length while retaining the original crop for review.B. Inspect boxes over headings and handwritten fields separately.C. Assign an address to its labeled field rather than concatenating all text on the page.D. Send ambiguous cases to a person with a clear correction path.

5. For review ambiguous scene predictions, which result or action fits this practical case: A scene label is uncertain because a sign is partly hidden.A. Inspect boxes over headings and handwritten fields separately.B. Validate a five-digit code against its expected length while retaining the original crop for review.C. Assign an address to its labeled field rather than concatenating all text on the page.D. Send ambiguous cases to a person with a clear correction path.
