FineReader Engine 11 Linux - Release 6 Update

  • Build #: 11.1.14.707470

This release is a patch to the latest official maintenance release of the product (FineReader Engine 11 R6), that contains speed optimizations due to new heap manager. Fine-tuning this distributive to Linux OS memory management specifics allowed us to overcome previous speed limitations.

The ‘heap’ is very common memory management paradigm in programming. For example, a good definition is provided here: “A very flexible storage allocation mechanism is heap allocation. Any number of data objects can be allocated and freed in a memory pool, called a heap. Heap allocation is enormously popular. Almost all non-trivial Java and C programs use new or malloc.”

We substituted the code used by one after Doug Lea. It turned out to be more efficient in case many small memory chunks are allocated. A speed up was gained for document analysis, recognition, and sometimes for synthesis plus PDF export steps. The speed up is not consistent and stable since it highly depends on an image/document complexity, available memory, and recognition route.

Release 6

  • FineReader Engine 11 Linux - Release 6 (available since 25.12.2015)

    • New export approach for large multi-page document conversion to searchable PDFs.
      The new export mode is almost 4 times faster as the default export method. It requires less RAM resources, makes the error handling more convenient and preservers losing all exported data in case of export error.
    • Smaller output PDF file size with pages of mixed colors.
      In combination with existing API for individual compression selection PDF exporting API allows now to reduce the file size of the exported PDF.
    • The predefined BarcodeRecognition_Accuracy profile provides more accurate results.
      The recognition accuracy of some barcodes has increased even by 20%.
    • Ability to process single-page documents from memory in batch mode.
      New API allows processing of single-page documents stored in memory in batch mode. It helps to comply to strict security standards as well as to increase the processing speed.
    • Correct processing of texts with different directionality.
      Updated properties for capturing the location of word’s characters now provide accurate results for both right-­to-­left and left-­to-right writing languages.
    • OCR improvements for Japanese, Arabic, Thai and Farsi.
      The improvements result in overall better recognition accuracy.
    • Possibility to implement own interface for managing the parallel processing.
      The developer has now the possibility to implement own logic for managing the parallel processing work and reporting errors which occurred during the processing.
    • Warnings are connected to particular pages.
      Now the warnings contain the page index information, which is useful in error-handling process.
    • Parallel multi-page image opening.
      Now ABBYY FineReader Engine can distribute opening of multi-page documents to CPU cores. New functionality brings up to 2 times speed-up for image opening step in 2 and 4 core configurations.
    • Exporting to ALTO up to version 3.0.
      Now it is possible to export OCR data into ALTO format according to the following ALTO standard versions: 2.0, 2.1, 3.0.
    • Possibility to save memory in case the information of coordinates on original image are not needed.
      If there is no need in keeping the information of coordinates on original image, the new property KeepOriginalCoordinatesInfo can be used for turning-off the storing this data. It might help to preserve storage and memory space, e.g. during processing of b/w images (~100Kb) the transformation data could be up to 1Mb per image.
    • Crop function for greyscale and black & white images.
      Now the Crop function supports greyscale and black & white images. Previously this function could be used only for color images.
    • New Java wrapper functions for loading Engine.
      Java wrapper contains new Engine loading functions, which now are capable to throw exceptions instead of logging them.
    • New property for fine-tuning of paper size detection.
      The FineReader Engine is able to detect paper boundaries on a scan automatically. It prevents that garbage near borders of a scan is detected as text. In some cases this detection can fail, e.g. if a scanned document contains a big dark picture. It might be taken as a scanning background and removed from a document area as a scanning shadow. To prevent such mistakes a host application may now advise the FineReader Engine to limit the scanning shadow detector hypotheses by providing information on what part a source document is located on a scan.
    • Visual quality improvement of exported PDFs with MRC compression.
      All predefined MRC modes (MinSize, MaxQuality, Balanced, MaxSpeed) have been improved in regard to visual quality.
    • New property for obtaining recognized word region.
      Many customers work with recognized words instead of recognized characters. In most cases, a word of matter usually needs to be highlighted in graphic user interface. The highlighting requires a word-bounding rectangle (region). Since words may include characters of different height and could span several lines the task becomes non-trivial. With help of the new property a word-bounding region can be obtained very easily.
