Question 1

A document management system uses 'zonal OCR.' What distinguishes zonal OCR from full-page OCR?

Accepted Answer

Zonal OCR extracts data from predefined regions of a form

Answer

Zonal OCR reads text only from specified areas of a document (e.g., fields on a form), enabling structured data extraction without processing the entire page.

Question 2

Which compression standard is most commonly used for bitonal (black-and-white) document images to achieve the highest compression ratios?

Accepted Answer

CCITT Group 4 (G4)

Answer

CCITT Group 4 compression is specifically designed for bitonal images and achieves very high compression ratios, making it the standard for scanned black-and-white documents.

Question 3

What is the main advantage of PDF/A over standard PDF for long-term document archiving?

Accepted Answer

PDF/A prohibits external dependencies and ensures self-contained, reproducible rendering

Answer

PDF/A is an ISO-standardized subset of PDF that prohibits features like encryption, external references, and embedded multimedia to ensure documents remain fully renderable long-term.

Question 4

In a high-volume production scanning environment, which scanner type is best suited for processing thousands of pages per day?

Accepted Answer

Production document scanner

Answer

Production document scanners are built for high-duty-cycle environments, handling thousands to tens of thousands of pages per day with high-speed ADFs and robust mechanisms.

Question 5

What does 'image segmentation' accomplish in an intelligent document processing workflow?

Accepted Answer

It separates an image into regions such as text blocks, graphics, and tables

Answer

Image segmentation identifies and classifies different regions within a scanned page (text, graphics, tables), enabling more accurate OCR and layout-aware processing.
