Tech Tip: OCR Speed and Accuracy
By: Connie Anderson
Technical Writer
When performing OCR (Optical Character Recognition) in the Laserfiche product suite, you can choose from several settings for speed or accuracy. This allows you to select the option that best suits the documents you are working with.
The OCR Optimization options are:
- Speed: Reduces the amount of time it takes to perform OCR. Generated text may be less accurate. You may want to choose this option if the image you are OCRing is clear and sharp, and you are OCRing large batches of documents.
- Balance/Standard: Neither optimum speed nor optimum accuracy, but between the two. This is the best choice for most people. Choose balance if you aren’t sure which option to choose.
- Accuracy: Helps perform OCR on images that have low accuracy with the other settings. Processing time will also be increased. You may want to choose this option if the image you are OCRing is fuzzy or unclear, or if you are getting poor OCR results from one of the other options.
The clearer the text on your documents, the more accurate the OCR is likely to be. Therefore, you may be able to use a faster OCR setting for documents with a high image quality and still get accurate results. Also, the fuzzy search setting in the Laserfiche Client can help you find documents even if the OCR is not 100% accurate. You can test the various settings on your documents and determine which works best for your purposes.
