Method Detail

getMinimumNumberOfRequiredFramesWithEqualRecognitionResult

public int getMinimumNumberOfRequiredFramesWithEqualRecognitionResult()

Minimum number of accumulated frames that have equal result

setMinimumNumberOfRequiredFramesWithEqualRecognitionResult

public void setMinimumNumberOfRequiredFramesWithEqualRecognitionResult(int value)

Minimum number of accumulated frames that have equal result

getMaximumNumberOfAccumulatedFrames

public int getMaximumNumberOfAccumulatedFrames()

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

setMaximumNumberOfAccumulatedFrames

public void setMaximumNumberOfAccumulatedFrames(int value)

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

getOcrResolutionLimit

public int 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

public void setOcrResolutionLimit(int value)

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.

getSupportedLanguages

@NotNull
public java.util.Set<io.scanbot.sdk.entity.Language> getSupportedLanguages()

Languages on which the recognition will be run

setSupportedLanguages

public void setSupportedLanguages(@NotNull
                                  java.util.Set<? extends io.scanbot.sdk.entity.Language> value)

Languages on which the recognition will be run

getMatchSubstringForPattern

public boolean getMatchSubstringForPattern()

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

setMatchSubstringForPattern

public void setMatchSubstringForPattern(boolean value)

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

getAllowedSymbols

@NotNull
public java.util.Set<java.lang.Character> getAllowedSymbols()

Allowed symbols to be detected

setAllowedSymbols

public void setAllowedSymbols(@NotNull
                              java.util.Set<java.lang.Character> value)

Allowed symbols to be detected

getTextFilterStrategy

@NotNull
public TextFilterStrategy getTextFilterStrategy()

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

setTextFilterStrategy

public void setTextFilterStrategy(@NotNull
                                  TextFilterStrategy value)

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

scanNv21

@Nullable
public GenericTextRecognitionResult scanNv21(@NotNull
                                                       kotlin.Array[] nv21,
                                                       int width,
                                                       int height,

                                                       android.graphics.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. Default is 0

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

setValidator

public void setValidator(@Nullable
                         java.lang.String validator,
                         @Nullable
                         io.scanbot.sdk.generictext.GenericTextRecognizer.GenericTextValidationCallback callback)

Sets the configuration to use during the validation

Parameters:

validator - sets a validation pattern (Supports ? - any character, # - any digit,all other characters represent themselves). Empty string or null will disable the validation)

callback - callback to validate a string in recognizer

setCleaner

public void setCleaner(@Nullable
                       io.scanbot.sdk.generictext.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

public void cleanRecognitionQueue()

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