AutoOCR / AutoOCR light 2.0 – iOCR innovations

Innovations AutoOCR / AutoOCR light Version 2.0:

  • The iOCR Standard OCR component of AutoOCR / AutoOCR light is now based on the new Tesseract OCR Version 4.0.
  • Multiple languages can be selected for OCR recognition.
  • Additional option to select OCR accuracy / speed.

  • Configurable parameter for splitting documents into smaller single documents to handle large page number documents with small / limited memory resources.

  • Conditional OCR processing – via file format, page number, page format – width / height in mm or pixels, resolution, file size and color depth – configurable for folder monitoring and web service processing. This can be controlled by file format per criteria – whether an OCR processing or conversion to a PDF image or whether the OCR processing of such files should be blocked. This can be prevented that the OCR processing is blocked by “meaningless” processing. for example if large JPEG photos get into the OCR processing process and handwriting recognition makes no sense.

Folder Monitoring – “File System Event” / “Blockwise Processing”

An application to monitor folders. For example AutoOCR / AutoOCRlight and so on, there are options that determine how the files are recognized for processing from the folders and when their processing is started.

File-System Event:

An operating system function is used to detect changes to files as well as new files in a folder / folder structure and to start processing immediately. This option should only be used for local folder / folder structures, but not for processing network shares.

Blockwise Processing:

The folder is read in “block by block”. That It always blocks in the set maximum number of files are read in and processed. After processing a “block” the next “block” starts etc. until all files have been processed. If no further files are found then the folder will be every 10msec. asked for new files. The “blockwise processing” should be used for folder monitoring of network drives.

Start of processing / delayed Start:

The processing of a newly detected file usually starts immediately, but there may also be reasons to delay the processing. For each watched folder, there is a setting to delay the start of processing by x seconds. First, the set time is waited in seconds and then processing is started – see also >>> – After the delay, the files to be processed are checked whether they are already free and not read-only. Here again max. 10sec. waited for the release of the file.

AutoOCR Version 1.17.2 – New function – delete empty pages

With AutoOCR version 1.17.2 there is an option to delete empty pages before OCR processing. The detection of a page as a “Blank” via a set threshold. The default value is 1%. A page is recognized as “empty” if less than 1% of the pixels of a page are “not white”. This value must be adjusted if necessary to be processed scans, as it may be when scanning with impurities also that a blank page having “more pixels”, and certain pages are then not detected as empty. However, if the threshold is set too high, it may be that pages with little content are also recognized as empty and thus deleted.

AutoOCR Version 1.17.2 – New iOCR Option – Do not or only partially embed fonts

Until now the used font was completely embedded in the created PDF’s. Therefore, especially with input files with one page always quite large PDF output files were generated. However, since the PDFs generated by AutoOCR use an image for display in the foreground and do not require fonts to display, we have changed that. By default, iOCR does not embed PDF fonts. There is the option to embed only the used part of the fonts. Thus, especially for documents that consist of only one or a few pages significantly smaller PDF files are created without embedded fonts.

AutoOCR Version 1.16.1 – New Option – Delayed Start of the Processing

An option was implemented in version 1.16.1, which made it possible to start the processing per monitored folder with a delay. This option is needed especially for multifunction devices which scan or copy a PDF or an image file directly into an AutoOCR monitored folder.

Certain multifunction devices create a file with 0-Byte, right at the start of a scan process, and either ‘fill’ it step by step with data or collect the scans locally on the device, to copy the finished complete file into the destination directory in the end. This process can take, depending on data volume, number of pages or speed of the data connection, between a few seconds and up to ten or more minutes.

So far, if the start delay is not activated (parameter = 0), AutoOCR starts the processing right away, when a file is created. If the file is not completely created or it is not ready for the processing, it will, within short intervals and with every access or process trial by AutoOCR, result in an error message in the log or in an error email. It can also lead to internal crashes of the OCR processing, which in turn triggers error messages, processing repeats and moves the input file to the error folder.

With this parameter it is possible to configure per folder, by how many seconds (0 to 999) the start of the processing should be delayed. A value has to be found, which complies with the requirements.

iOCR / vsOCR Setup divided into standard and additional languages

The iOCR / vsOCR setup containing the language and dictionary files of our standard OCR engine is more than 270MB in size. In order to make the downloads and the setups smaller, we decided to split the iOCR / vsOCR into a “base” and an “additional setup”. The basic setup, which is available through our applications, eg. AutoOCR, FileConverterPro, or PDFmdx now only contains a selection of major European languages and has been reduced to 127MB.

If all available languages are to be installed, this is possible at any time. The additionally available “exotic languages” can be installed via a separate setup.

iOCR Basic-languages:

Danish, German, English, Finnish, French, Italian, Catalan, New Greek, Dutch, Norwegian, Polish, Portuguese, Romanian, Russian, Swedish, Slovakian, Slovenian, Spanish, Czech, Turkish, Ukrainian, Hungarian

iOCR extende languages:

Afrikaanis, Albanian, Arabic, Azerbaijani, Bahasa Indonesian, Bengali, Bulgarian, Cherokee, Chinese – Traditional, Chinese – Simplified, Estonian, Franconian, Gallic, Hebrew, Hindi, Icelandic, Japanese, Korean, Croatian, Latvian, Lithuanian, Macedonian, Malay , Serbian, Swahili, Tagalog, Tamil, Telugu, Thai, Vietnamese, Belarusian

AutoOCR – Installation requirements from version 1.15.3

With the AutoOCR installation from version 1.15.3, modified installation prerequisites are checked – if these are fulfilled, these installation steps are skipped by the setup and are not executed.

The following components are checked and, if necessary, post-installed:

If these components are already installed, they are not reloaded and only AutoOCR is installed. If all or individual components are not available or not in the appropriate version, the AutoOCR Setup tries to download them from our FTP server and install them. If an installation is to be made without an Internet connection, the setups of these components should be downloaded and installed beforehand.

The AutoOCR settings and the license are retained when uninstalling / updating the new version.

AutoOCR can be operated with one or more different OCR engines. The iOCR (vsOCR) processing is standard.

In addition, or even only, the Abbyy OCR for AutoOCR can be used as an option. However, an additional Abbyy setup must be downloaded and installedFor the Abbyy OCR Engine version 10 demo licenses are available for 30 days or 500 pages – which you can request from us.

If only the Abbyy OCR engine is to be used, the download and installation of iOCR can be skipped during setup.

AutoOCR Version 1.15.3 available

Innovations AutoOCR Version 1.15.3:

  • New iOCR EngineWe replaced the previous standard iOCR engine with a new product – vsOCR –. This results in a better detection rate as well as a significantly better performance for multicore / multiprocessor computers. With the new OCR Engine, we now support parallel / multithread processing with multi-page TIFF and PDF documents. The OCR processing speed is thereby multiplied, if, for example, 4 or 8 cores are available.

Setup Option - iOCR herunterladen und installieren

  • iOCR – PDF rendering resolution configurableSince only image / image documents can be processed by OCR, PDF documents are always subjected to an image (rendering) prior to OCR processing. There is now the possibility to configure the rendering resolution for SW and color, whereby the default value for SW and color is 300dpi.

iOCR - Option - PDF Rendering resolution for b&w and color

  • Abbyy OCR – New default settingsBased on our experience so far, we have redefined the default settings to achieve the best possible recognition rate as well as the highest possible OCR performance. A single option can affect the processing speed, especially for multi-page documents with a lot of text by a factor of 5 or 10 or moreA 10 page document can be stored in either 10 sec. or in 5 min. depending on whether the “Recognize font formatting” option is enabled or not.

  • Remove black border –  Was added as a new general image processing function for iOCR and Abbyy. Thus, a possible black border is detected and removed in all documents before OCR processing. The page size is not changed.

Neue Option - schwarzen Rand entfernen

  • Configure an invalid license responseStopping the service (default value) or demo stamp on the document.

  • Further adjustmentsAutostart of the AutoOCR User Interface – is now activated by default. Error while creating the optional TXT file with iOCR has been fixed. Read-only PDF documents do not produce endless loops when processing. The temporary Abbyy Folder is now correctly deleted after the set number of days. Language-specific special characters are now encoded correctly with the Abbyy PDF/A output.

AutoOCR – Folder processing / monitoring – what to consider?

Features – AutoOCR processing / monitoring folders:

1.) Processing input folders / structures: Here an input folder or an entire folder structure is processed. The generated PDF files are stored in the same folder structure with the same name as the original fileHowever, a special case, PDF files, as there are PDF files which do not require OCR processing and others which require one. It may also happen that only certain pages of a PDF file need to OCR processing.

In order not to process the PDF’s again that have already been processed by AutoOCR files are indicated in the data structure by a label”.

At the start of the service AutoOCR the folder structure completely scanned to identify backlogged files. Each PDF file needs to be checked for this “label”. It should be noted that with large data sets, this process takes a long time since any PDF file must be opened and checked.

2.) retain date / time of the original file: With this option, the date and time of creation, modification, and last access can be transmitted from the source file to the generated by OCR PDF file. The PDF document is thus replaced without changing the attributes.

Option um die Datums und Uhrzeit der Urspungsdatei zu erhalten

3.) Smart OCR processing of PDF files: PDFs can be pure image files without text, normal” PDF files that already contain text or be mixed documents. Here individual pages are scanned image files with no text and the remaining pages are normal PDF content with text. Without special functionality always the whole PDF document will be OCR processed and so all pages regardless of the content. This takes time, resources and increases the PDF files unnecessarily. That is why you should activate the intelligent OCR processing. Only those documents and pages OCR be processed, where it is necessary. Normal” PDF files are not processed, but only marked with a label” see 1.).

4.) Folder Monitor File System Events / block processing: If it is required that during the current processing newly added files are immediately detected and processed, so the “File System Eventsmust be selectedIf selected block processing“, so newly added files are not automatically detected. The block processingis specifically designed for the initial processing of large volumes of documents. After the initial processing should then be switched to file system eventsso that newly added files are immediately processed. If the AutoOCR service stopped and restarted, the complete folder structure is searched for unprocessed files first always.

5.) Process files / folders from network shares: After installing the AutoOCR service runs by default as “Local System Account”. Must to files and folders are handled by the network shares, allowed so you have to create a user account” to be used for the AutoOCR service which also has the appropriate rights to access the network shares used access.
