ABBYY FineReader Engine 8.0 EPS

Key Features

Image Manipulation and Pre-processing

ABBYY FineReader Engine can receive images by two ways: getting directly from memory or opening from files. It supports major imaging formats, including multi-page TIFFs, JPEG 2000 (part 1), and works with black-and-white, grayscale and color images. It also can open PDF files, converting them into images using Adobe® PDF Library Technology.
The FineReader Engine may also save original and modified images into various formats. For the full list of supported image formats, see the Specifications section.

Upon receiving images, the FineReader Engine can perform the following preprocessing functions to improve the recognition:

Automatically de-skew images
This feature is essential to be used especially when images come from scanners and requires a compensation for image skew. It does not require leading edge borders or lines.
Split dual pages
Works for scanning books as broadsides - both the left and right pages. The recognition quality is higher if, after scanning, the page is split into two, with each page corresponding to a single book page. Recognition and layout analysis are then performed separately for each page, along with de-skewing if required.
Despeckle image (or image clean-up)
Designed to eliminate random noise (speckles). The image may have a large amount of "dust" present on it, i.e. a large number of excess dots. The dots arise in the case of documents of medium-to-low print quality, and dots located close to character outlines may have an adverse effect on recognition quality. These cases despeckle technique helps to improve the recognition quality.
Texture Filtering and Adaptive binarization
Texture filtering technology helps to filter out background "noise" such as color and texture, increasing accuracy for difficult-to-read documents such as newsprint, color documents, faxes, and copies.

Innovative Adaptive Binarization technology dynamically adjusts threshold of brightness for each image fragment during the recognition. And by this usage of individual recognition parameters it produces significantly accurate recognition results for documents with gray or color variable contrast background and textures.

Auto-detection of page orientation (90, 180, 270 degrees).
This feature is very important when in a bulk imputing system it is unknown on which direction the image is scanned. The FineReader system automatically detects the orientation of each page and corrects it, if needed.
Manipulating with text color and background manipulation inside rectangles.
It is an important feature for customers working with document management systems (DMS). The typical scenario of using this feature in archiving business is the following. A recognized image is stored as image and as plain text in an archive. Archive index of text also contains the coordinates if each character on the image. When a user receives a result of searching through archive, he gets an image of document as a source. But on that image, using the mentioned FineReader Engine function, the searching text is highlighted, changing the text color and background color within a rectangle, which completely outlines a found text.
Adaptive image pre-processing for camera images. The new technology applies different processing algorithms and correct specific image distortion typically seen in digital camera images. This provides an average improvement of 40% better accuracy in digital camera OCR.
Despeckling of an image in individual blocks (or zones), with the ability to specify the size of black dots.

The FineReader Engine also offers a number of useful pre-processing functions, allowing to manipulate images such as "image scaling", "image clipping", "creating previews", "rotating (90, 180, 270 degrees)", "mirroring" and "inverting".

Document Analysis and Full Layout Retention

The document analysis function set of FineReader Engine API solves such tasks as automatic document conversion with full-page layout retention, zoning OCR with manually located blocks, etc. It includes:

auto-detection of page orientation - 90, 180, 270 degrees (see above in Image Manipulation and Pre-processing);
auto-detection of text blocks, tables, barcodes and pictures;
auto-detection of vertical text in table cells;
manual block zoning (adding, removing and editing blocks);

The unique FineReader Engine features are:

Document Analysis for Archiving Tasks
This function automatically detects and recognizes all text on documents including text embedded in pictures, charts, and diagrams. Developers may choose to use this mode of document analysis to extract exhaustive full-text information on documents needed for document index building (as in DMS, CMS, Archiving systems).
Document Analysis for Invoices
A special document analysis function designed as a preprocessing engine for converting semi-structured documents, such as invoices, payment drafts, checks, transfers, business cards, agreement, health claim forms, resumes, etc. In this preprocessing role, this function has been designed to find as much text on these documents as possible, including characters and numbers — even if this information is located within stamps, pictures, logos or small-text areas. Unlike in standard full-page document analysis, this specialized document analysis assumes all printed information on the documents is text. It also ensures that important text information is not identified as graphic elements and that words or numerical values are not separated into multiple characters. As a result, maximum information about the text, including its coordinates, is available for analysis, field-by-field processing and parsing at subsequent processing stages by other systems.
Export to Multiple Formats including PDF, RTF/DOC/WordML, XML, and HTML with exact layout retention.

Recognition

Field-level/Zonal Recognition Support

The SDK provides powerful field-level/zonal recognition capabilities ensuring accuracy and speed enhancement on small fields/zones. This functionality is crucial for processing tasks like data extraction, key-word indexing, and keyword classification. Key functionality for field level or zonal recognition includes multilingual OCR and barcode recognition, including:

* Definition of field content by setting alphabets and dictionaries.

* Detection of in-filed spacing - Detection and recognition of fields where the spaces are allowed. The FineReader Engine 8.0 also allows use of dictionaries which contain word-combinations with spaces.

* Text block despeckle, with the ability to specify the size of white or black «garbage».

* External recognition tuning features - Provides integrators with multiple word-level and character-level hypothesis and allowing integrators to influence the hypothesis choice by inserting additional ranking criteria during the recognition process.

PDF Conversion

The SDK includes powerful PDF conversion technology with extensive functions for PDF input and output including:

PDF Input

Fast and accurate PDF processing. Analyses of internal information within the source PDF files such as annotations, metadata, text objects, font dictionaries and content streams and as a result enhances PDF performance and speed by efficient and accurate selection. When the text is embedded, examines the integrity of the text layer, and makes a decision as to whether or not to extract the text or apply OCR on a block by block basis.
Capture of Internal PDF Information, extracting internal PDF links, hyperlinks and document properties such as: subject, author, title, and keywords.
