Question 1

Which metric is most commonly used to measure the accuracy of OCR output during document imaging quality control?

Accepted Answer

Character error rate (CER)

Answer

Character error rate (CER) measures the percentage of incorrectly recognized characters in OCR output, making it the standard QC accuracy metric.

Question 2

In document imaging QC, what does a 'dropout color' technique accomplish?

Accepted Answer

Removes background form lines from scanned images

Answer

Dropout color filtering removes preprinted form lines or backgrounds during scanning, leaving only the handwritten or typed content.

Question 3

What is the purpose of a rescan threshold policy in a document imaging quality program?

Accepted Answer

To define the acceptable defect rate before a batch must be rescanned

Answer

A rescan threshold policy specifies the defect percentage at which an entire batch is rejected and must be rescanned rather than corrected page by page.

Question 4

Which type of QC sampling is most appropriate when a document imaging project has a very large volume and 100% inspection is not feasible?

Accepted Answer

Statistical sampling

Answer

Statistical sampling applies probability theory to select a representative subset, enabling reliable quality estimates without inspecting every document.

Question 5

During image quality inspection, 'skew' refers to which document defect?

Accepted Answer

The page is captured at an angle rather than straight

Answer

Skew occurs when a document is not fed straight through the scanner, resulting in a tilted image that may affect readability and OCR accuracy.
