Tech Tip: OCR Speed and Accuracy
February 17th, 2010 Comment on this articleWhen 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.
In the Laserfiche 8 product suite, the OCR Optimization options are:
- Speed: Reduces the amount of time it takes to perform OCR. Generated text may be less accurate.
- Balance/Standard (Recommended): Neither optimum speed nor optimum accuracy, but a balance between the two.
- Accuracy: Helps perform OCR on images that have low accuracy with the other settings. Processing time will also be increased.
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.
NOTE: The version of the OmniPage OCR engine has changed for all Laserfiche products released at or after Client 8.1. The Balance/Standard option in the current version of the engine is equivalent to the Accuracy setting in products released from 7.2.1 to 8.0.x. Therefore, if you were having good results with OCR set to Accuracy in those versions, you may want to set it to Balance in Laserfiche 8.1.
To change the OCR Optimization setting in the Laserfiche 8.1 Client:
- From the Tools menu, select Options and OCR.
- For Optimization priority, select Accuracy, Balance, or Speed.
- You can also access this setting by selecting Options from the Generate Searchable Text dialog box.
When working with Laserfiche Scanning or Quick Fields, you can set the optimization properties while configuring the OCR process.
