ReceiptRecognitionSettings

public ReceiptRecognitionSettings()

Default constructor: set autoSkew true.

Method Detail

setLanguage

public void setLanguage(Language language)

Parameters:

language - Sets the language used for OCR. Multi-language (none) by default.

setIgnoredCharacters

public void setIgnoredCharacters(String characters)

Sets blacklist for recognition symbols.

Parameters:

characters - Characters excluded from recognition.

setThreadsCount

public void setThreadsCount(int threadsCount)

Gets or sets the number of 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.

Parameters:

threadsCount - the number of threads that will be created for parallel recognition of image fragments.

setAllowedCharacters

public void setAllowedCharacters(CharactersAllowedType allowedCharacters)

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

Parameters:

allowedCharacters - contains enum @see CharactersAllowedType value.

setAllowedCharacters

public void setAllowedCharacters(String allowedCharacters)

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

Parameters:

allowedCharacters - contains array of characters.

setUpscaleSmallFont

public void setUpscaleSmallFont(boolean upscaleSmallFont)

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

Parameters:

upscaleSmallFont - contains boolean value - a upscaleSmallFont is set.

setAutomaticColorInversion

public void setAutomaticColorInversion(boolean automaticColorInversion)

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

Parameters:

automaticColorInversion - contains boolean value - a automaticColorInversion is set.

setLanguageDetectionLevel

public void setLanguageDetectionLevel(LanguageDetectionLevel languageDetectionLevel)

Specifies the level of language detection for text recognition. Works only if the selected language is Language.MULTILANGUAGE, Language.AUTO, or Language.UNIVERSAL. This process is time-consuming and significantly slows down the overall recognition.

Parameters:

languageDetectionLevel - enum value to set level (Paragraph, Word, Page).
