What are the Disadvantages of a OCR?

Answer 1

While OCR (Optical Character Recognition) offers many benefits, it also comes with some limitations and disadvantages:

Accuracy Issues with Poor-Quality Inputs:

OCR struggles with low-resolution images, smudged text, or handwritten documents, leading to inaccurate character recognition.

Limited Understanding of Context:

Traditional OCR reads characters but doesn’t understand context, meaning it can misinterpret similar-looking characters (like “0” and “O” or “I” and “1”).

Lack of Formatting Recognition:

OCR often fails to preserve document layout, tables, or formatting, especially in complex documents.

Language and Font Limitations:

OCR systems may not support all languages or uncommon fonts, reducing their versatility.

High Error Rates in Complex Documents:

Documents with graphics, multiple columns, or non-standard layouts can result in higher error rates.

Manual Verification Still Needed:

Due to potential errors, manual review and correction are often required, especially for critical data.

Security Risks:

If not properly handled, scanned documents may contain sensitive data that could be at risk during OCR processing.
