• DefaultGenericTextRecognizer

  DefaultGenericTextRecognizer(BlobManager blobManager)

Method Detail

• getMinimumNumberOfRequiredFramesWithEqualRecognitionResult

   Integer getMinimumNumberOfRequiredFramesWithEqualRecognitionResult()

  Minimum number of accumulated frames that have equal result

• setMinimumNumberOfRequiredFramesWithEqualRecognitionResult

   Unit setMinimumNumberOfRequiredFramesWithEqualRecognitionResult(Integer minimumNumberOfRequiredFramesWithEqualRecognitionResult)

• getMaximumNumberOfAccumulatedFrames

   Integer getMaximumNumberOfAccumulatedFrames()

  Maximum number of accumulated frames to inspect before actual result is returned

• setMaximumNumberOfAccumulatedFrames

   Unit setMaximumNumberOfAccumulatedFrames(Integer maximumNumberOfAccumulatedFrames)

• getOcrResolutionLimit

   Integer getOcrResolutionLimit()

  The image will be downscaled to the given value during the processing. If the quality of the scanning is not enough, try to increase the limit. This variable affects the performance of the scanning process. Higher the size limit - better the quality, but the recognition is slower

  0 - do not rescale.

• setOcrResolutionLimit

   Unit setOcrResolutionLimit(Integer ocrResolutionLimit)

• getSupportedLanguages

   Set<Language> getSupportedLanguages()

  Languages on which the recognition will be run

• setSupportedLanguages

   Unit setSupportedLanguages(Set<Language> supportedLanguages)

• getAllowedSymbols

   Set<Character> getAllowedSymbols()

  Allowed symbols to be detected

• setAllowedSymbols

   Unit setAllowedSymbols(Set<Character> allowedSymbols)

• getMatchSubstringForPattern

   Boolean getMatchSubstringForPattern()

  Find and match only part of the whole string if the pattern is used

• setMatchSubstringForPattern

   Unit setMatchSubstringForPattern(Boolean matchSubstringForPattern)

• getTextFilterStrategy

   TextFilterStrategy getTextFilterStrategy()

  Additional parameter to set the type of the scanned object. TextFilterStrategy.Document by default

• setTextFilterStrategy

   Unit setTextFilterStrategy(TextFilterStrategy textFilterStrategy)

• scanNv21

   GenericTextRecognitionResult scanNv21(ByteArray nv21, Integer width, Integer height, Integer orientation, Rect finderRect)

  Scan image to recognize text on it

  Parameters:

  nv21 - image in form of nv21-encoded byte array

  width - image width, pixels

  height - image height, pixels

  orientation - image orientation.

  finderRect - if non-null - perform scanning only in given area.

• setValidator

   Unit setValidator(String validator, GenericTextRecognizer.GenericTextValidationCallback callback)

  Sets the configuration to use during the validation

  Parameters:

  validator - sets a validation pattern (Supports ?

  callback - callback to validate a string in recognizer

• setCleaner

   Unit setCleaner(GenericTextRecognizer.CleanRecognitionResultCallback callback)

  Sets the cleaner for the raw text to prepare the raw recognized string to validation. Allows to increase the quality and speed of the recognition

  Parameters:

  callback - callback to clean the raw text extracted from the picture and to extract only valuable part from it

• cleanRecognitionQueue

   Unit cleanRecognitionQueue()

  Allows to clean the accumulated frames inside the recognizer. Should be called if reusing the instance after getting the successful result
