Which metric is most commonly used to measure the accuracy of OCR output during document imaging quality control?
Answer: Character error rate (CER)
Character error rate (CER) measures the percentage of incorrectly recognized characters in OCR output, making it the standard QC accuracy metric.
In document imaging QC, what does a 'dropout color' technique accomplish?
Answer: Removes background form lines from scanned images
Dropout color filtering removes preprinted form lines or backgrounds during scanning, leaving only the handwritten or typed content.
What is the purpose of a rescan threshold policy in a document imaging quality program?
Answer: To define the acceptable defect rate before a batch must be rescanned
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.
Which type of QC sampling is most appropriate when a document imaging project has a very large volume and 100% inspection is not feasible?
Answer: Statistical sampling
Statistical sampling applies probability theory to select a representative subset, enabling reliable quality estimates without inspecting every document.
During image quality inspection, 'skew' refers to which document defect?
Answer: The page is captured at an angle rather than straight
Skew occurs when a document is not fed straight through the scanner, resulting in a tilted image that may affect readability and OCR accuracy.
What is a key benefit of automated quality control over manual QC in large-scale document imaging projects?
Answer: Consistent application of inspection criteria without human fatigue
Automated QC applies the same inspection rules consistently across millions of images, whereas manual reviewers are susceptible to fatigue-induced inconsistency.
In the context of CDIA quality control, what does 'indexing accuracy' measure?
Answer: The correctness of metadata assigned to scanned documents
Indexing accuracy measures how correctly document metadata fields—such as document type, date, or ID number—are populated during the imaging process.
