OCR engines available for document digitization in Document Understanding, with supported image resolution ranges and guidance on selecting the appropriate engine.
An OCR Engine is used in the Digitization component, to identify text in a file, when native content is not available.
Note:
The images that need to be processed should have a resolution range of:
- min: 50 x 50 pixels
- max: 9000 x 9000 pixels
Here is a selection of OCR Engines that you can choose from, according to your needs, throughout the Document UnderstandingTM Framework.
