ABBYY FineReader Engine

A software development kit that allows software developers to create applications that extract textual information from paper documents or images. Alias FineReader Engine, FRE, FREngine.

API

Application Programming Interface. Learn more: Wikipedia.

Binarization or Adaptive Binarization

The process of converting a grey-scale or color image into black-and-white image. When recognizing a document, this process helps to dynamically adjust the brightness balance for each image fragment.

Block

An internal entity of the ABBYY FineReader Engine API that defines the area of the source image and its type (text, barcode, checkmark, etc.). Blocks can be marked manually or created automatically after document analysis. Blocks determine how and in what order the image areas to be recognized and after recognition contain its results. Learn more: Block, Working with Layout and Blocks.

CJK or CJK languages

Chinese (Simplified and Traditional), Japanese, and Korean languages. Learn more: Recognizing CJK Languages.

CLI

Command-line interface. To see how it is implemented in ABBYY FineReader Engine, you may use the appropriate code sample included in the distribution package. This code sample supports most of the ABBYY FineReader Engine API functions through numerous option keys.

Confidence level

The probability of using a particular character in a text. Learn more: Using Voting API.

Confusion matrix or error matrix

A table representing the results of an algorithm used for object classification. Learn more: Wikipedia, ConfusionMatrix.

Container

A software unit with an entire runtime environment inside using to pack an application with all its dependencies to ensure stable operating in various computing environments. Learn more: Docker website, Running ABBYY FineReader Engine 12 inside a Docker container.

Counter or License Counter

A license entity for the limitation of the pages or characters recognized and exported during a certain period.

The step of OCR responsible for detecting the elements of document structure and creating a layout that exposes a collection of blocks. Learn more: Document Analysis, Working with Layout and Blocks.

Dpi

Dots per inch. Learn more: Wikipedia.

EULA

End-User License Agreement. This document is included in the ABBYY FineReader Engine distribution package or can be accessed via online help. Learn more: Wikipedia.

EXIF

Exchangeable image file format. A standard describing specific data that comes along with an image or audio file captured by a digital camera (for example, GPS location, date/time, camera settings, etc.). Learn more: Wikipedia.

Extraction

The process of data mining from pictures or texts. This process is applied to the scenarios of recognizing the texts, barcodes, fields, or MRZ. Additionally, extraction is used to retrieve additional objects on the images. Learn more: ObjectExtractionParams.

Hypothesis

A recognition variant of a single character or word in a text. Each hypothesis has a confidence level that is useful in situations when it is necessary to select the most appropriate variant among several. Learn more: Using Voting API.

ICAO

International Civil Aviation Organization. An organization that determines the standards and specifications for machine-readable travel documents. Learn more: ICAO website.

ICR

Intelligent Character Recognition. The technology used for the recognition of the characters that are hand-printed and separated into individual characters. These characters are to be detected in fields, boxes, and frames of the documents. Learn more: OCR and Other Recognition Technologies, Recognizing Handprinted Texts.

InprocLoader

An object that allows to load and unload ABBYY FineReader Engine as an in-process server (as DLL) in the same process as a client. The communication between the client and in-process server is based on direct calls into an object implementation.

Library module

A set of License modules forming the ABBYY FineReader Engine function available for the user and determining the files required to perform this function. Learn more: Library modules.

License module

A licensing entity used for providing access to a certain functionality of ABBYY FineReader Engine. Each License module corresponds to a certain Library modules to be installed. Learn more: Modules.

License Server

A separate workstation used for installing and managing the ABBYY FineReader Engine licensing components: the Licensing Service and the License Manager utility. License Server is required when using a Network License to distribute your license to the workstations over the network. The License Manager utility allows you to manage ABBYY FineReader Engine licenses of all types through graphic user interface or command-line interface. Learn more: Licensing.

Ligature

A character formed by combining two or more characters. Learn more: Wikipedia, Training User Patterns.

Loaders or Engine loaders

The interfaces and objects for initializing the main Engine object of the ABBYY FineReader Engine API. There are several ways to load the Engine object on various operating systems:

Windows Linux Mac
Standalone Application
  • By using standard InitializeEngine function
  • By means of COM using InprocLoader
By using standard InitializeEngine function

By using standard InitializeEngine function

Server Solution By means of COM using OutprocLoader As an out-of process server Not supported

To choose what is preferable for your scenario (single-threaded or multi-threaded application, in-process or out-of-process loading, working with GUI, etc.), see Different Ways to Load the Engine Object.

MRC

Mixed Raster Content. This technology can be applied to PDF (PDF/A) files and represents a document as three different layers: the first one is a foreground plane with pictures, the second one is a mask plane with the text and its coloring, and the third one is a background plane with background pictures or textures. Each layer is compressed separately using the best type of compression for that data type. Learn more: PDF Conversion.

OBR

Optical Barcode Recognition. The process of automatic detection, recognition, and identification of barcode on an image. Learn more: OCR and Other Recognition Technologies, Barcode Types, Recognizing Barcodes.

OCR
