Quality of text recognition in OCR webservice improved

Also existing functions, like the recognition of text (OCR) in PDF documents or graphics will be improved with the latest update of webPDF (Revision No. 2159). We now offer the possibility to prepare (optimize) your document before recognition in order to optimize the result.

By applying various graphic operations to the source document (graphic or PDF), an improved basic document for the actual Optical character recognition is created.

The new options allow you to brighten and sharpen images and PDF documents, remove unwanted elements automatically and more. These optimizations are all only temporarily active during text recognition, so your source document remains unchanged.

The recognition results can therefore be greatly improved, especially with difficult documents that are blurred or have many disturbing elements in the background.

These new (optional) operations are supported via the OCR webservice of the webPDF server and via the dialog “Text recognition” in the portal under the tab “Optimization”.
