Method Detail

• scanNv21

   abstract 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

   abstract Unit setValidator(String pattern, GenericTextRecognizer.GenericTextValidationCallback callback)

  Sets the configuration to use during the validation

  Parameters:

  pattern - sets a validation pattern (Supports ?

  callback - callback to validate a string in recognizer

• setCleaner

   abstract 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

   abstract Unit cleanRecognitionQueue()

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

• getMinimumNumberOfRequiredFramesWithEqualRecognitionResult

   abstract Integer getMinimumNumberOfRequiredFramesWithEqualRecognitionResult()

  Minimum number of accumulated frames that have equal result.

• setMinimumNumberOfRequiredFramesWithEqualRecognitionResult

   abstract Unit setMinimumNumberOfRequiredFramesWithEqualRecognitionResult(Integer minimumNumberOfRequiredFramesWithEqualRecognitionResult)

  Minimum number of accumulated frames that have equal result.

• getMaximumNumberOfAccumulatedFrames

   abstract Integer getMaximumNumberOfAccumulatedFrames()

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

• setMaximumNumberOfAccumulatedFrames

   abstract Unit setMaximumNumberOfAccumulatedFrames(Integer maximumNumberOfAccumulatedFrames)

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

• getOcrResolutionLimit

   abstract 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

   abstract Unit setOcrResolutionLimit(Integer ocrResolutionLimit)

  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.

• getMatchSubstringForPattern

   abstract Boolean getMatchSubstringForPattern()

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

• setMatchSubstringForPattern

   abstract Unit setMatchSubstringForPattern(Boolean matchSubstringForPattern)

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

• getAllowedSymbols

   abstract Set<Character> getAllowedSymbols()

  Allowed symbols to be detected.

• setAllowedSymbols

   abstract Unit setAllowedSymbols(Set<Character> allowedSymbols)

  Allowed symbols to be detected.
