BaseRecognitionSettings(Language)

Initializes a new instance of the Aspose.OCR.RecognitionSettings class with full set of properties.

public BaseRecognitionSettings(Language language = Language.Latin)

Parameters

language Language

Language used for OCR.

Properties

AllowedCharacters

Allowed characters set. Determines the type of characters allowed for recognition result.

public CharactersAllowedType AllowedCharacters { get; set; }

Property Value

CharactersAllowedType

AllowedSymbols

Set the allowed characters with alphabet property.

public string AllowedSymbols { get; set; }

Property Value

string

AutomaticColorInversion

Detect images with white text on dark/black background and automatically choose a special OCR algorithm for them.

public bool AutomaticColorInversion { get; set; }

Property Value

bool

DetectAreasMode

Allows to select the optimal mode for document type areas: document, photo, plain text, column, image.

public DetectAreasMode DetectAreasMode { get; set; }

Property Value

DetectAreasMode

IgnoredSymbols

Sets blacklist for recognition symbols.

public string IgnoredSymbols { get; set; }

Property Value

string

Language

Gets or sets the language used for OCR. Determines the alphabet used during recognition. Multi-language by default.

public Language Language { get; set; }

Property Value

Language

LanguageDetectionLevel

Specifies the level of language detection for text recognition. Works only if the selected language is Aspose.OCR.Language.Multilanguage, Aspose.OCR.Language.Auto, or Aspose.OCR.Language.Universal. This process is time-consuming and significantly slows down the overall recognition.

public LanguageDetectionLevel LanguageDetectionLevel { get; set; }

Property Value

LanguageDetectionLevel

LinesFiltration

Allows to recognize text in the tables (regions surrounded lines).

public bool LinesFiltration { get; set; }

Property Value

bool

ThreadsCount

Gets or sets the number fo threads for processing. By default, 0 means that the image will be processed with the number of threads equal to your number of processors. ThreadsCount = 1 means that the image will be processed in the main thread.

public int ThreadsCount { get; set; }

Property Value

int

UpscaleSmallFont

Allows you to use additional algorithms specifically for small font recognition. Useful for images with small size characters.

public bool UpscaleSmallFont { get; set; }

Property Value

bool
