Acceptable OCR accuracy rates Good OCR accuracy= 98-99% accurate(1-2% of OCR incorrect)Average OCR accuracy= 90-98% accurate(2-10% of OCR incorrect)Poor OCR accuracy= below 90% accurate(more than 10% of OCR incorrect)
How to correct OCR errors Open your OCRd document in Acrobat. In the right-hand Tools panel search for Correct and select the Correct Recognized Text option beneath Enhance Scans. The Correct Text function will appear at the top of your screen. Check Review recognized text.
Optical Character Recognition (OCR) is the process that converts an image of text into a machine-readable text format. For example, if you scan a form or a receipt, your computer saves the scan as an image file. You cannot use a text editor to edit, search, or count the words in the image file.
PDF (Portable Document Format) A PDF file is among the most commonly used file types. This file type is great for documents with text, forms, and images that contain words. Certain programs use OCR technology to make the characters in the document searchable and editable.
Digitizing Your Documents The recommended resolution for scanning documents for optimal OCR accuracy is 300 dots per inch (dpi). Brightness settings that are too high or too low can cause defects to the text (overexposure or obscuring, respectively) and reduce the accuracy of your image.
Measuring OCR accuracy is done by taking the output of an OCR run for an image and comparing it to the original version of the same text. You can then either count how many characters were detected correctly (character level accuracy), or count how many words were recognized correctly (word level accuracy).
Obviously, the accuracy of the conversion is important, and most OCR software provides 98 to 99 percent accuracy, measured at the page level. This means that in a page of 1,000 characters, 980 to 990 characters will be accurate. In most cases, this level of accuracy is acceptable.
