Detailed Description

QualitySettings allows to configure recognition quality and speed manually.

You can quickly set up QualitySettings by embedded presets: HighPerformance, NormalQuality, HighQuality, MaxBarCodes or you can manually configure separate options. Default value of QualitySettings is NormalQuality. This sample shows how to use QualitySettings with BarCodeReader

reader = Recognition.BarCodeReader("test.png", None,  [ DecodeType.CODE_39_STANDARD, DecodeType.CODE_128 ])
#set high performance mode
reader.setQualitySettings(QualitySettings.getHighPerformance())
for result in reader.readBarCodes():
   print("BarCode CodeText: " + result.getCodeText())

reader = Recognition.BarCodeReader("test.png", None,  [ DecodeType.CODE_39_STANDARD, DecodeType.CODE_128 ])
#normal quality mode is set by default
for result in reader.readBarCodes():
  print("BarCode CodeText: " + result.getCodeText())

reader = Recognition.BarCodeReader("test.png", None,  [ DecodeType.CODE_39_STANDARD, DecodeType.CODE_128 ])
#set high quality mode with low speed recognition
reader.setQualitySettings(QualitySettings.getHighQuality())
for result in reader.readBarCodes():
  print("BarCode CodeText: " + result.getCodeText())

reader = Recognition.BarCodeReader("test.png", None,  [ DecodeType.CODE_39_STANDARD, DecodeType.CODE_128 ])
#set max barcodes mode, which tries to find all possible barcodes, even incorrect. The slowest recognition mode
reader.setQualitySettings(QualitySettings.getMaxBarCodes())
for result in reader.readBarCodes():
  print("BarCode CodeText: " + result.getCodeText())

reader = Recognition.BarCodeReader("test.png", None,  [ DecodeType.CODE_39_STANDARD, DecodeType.CODE_128 ])
#set high performance mode
reader.setQualitySettings(QualitySettings.getHighPerformance())
#set separate options
reader.getQualitySettings().setAllowMedianSmoothing(true)
reader.getQualitySettings().setMedianSmoothingWindowSize(5)
for result in reader.readBarCodes():
    print("BarCode CodeText: " + result.getCodeText())

reader = Recognition.BarCodeReader("test.png", None,  [ DecodeType.CODE_39_STANDARD, DecodeType.CODE_128 ])
#default mode is NormalQuality
#set separate options
reader.getQualitySettings().setAllowMedianSmoothing(true)
reader.getQualitySettings().setMedianSmoothingWindowSize(5)
for result in reader.readBarCodes():
  print("BarCode CodeText: " + result.getCodeText())

Constructor & Destructor Documentation

__init__()

def __init__	(		self,
			qualitySettings
	)

Reimplemented from BaseJavaClass.

Member Function Documentation

applyAll()

def applyAll	(		self,
			Src
	)

Function apply all values from Src setting to Dst :

Parameters

Src	Src source settings

getAllowIncorrectBarcodes()

def getAllowIncorrectBarcodes

(

self

)

Allows engine to recognize barcodes which has incorrect checksumm or incorrect values.

Mode can be used to recognize damaged barcodes with incorrect text. :#return: Allows engine to recognize incorrect barcodes.

getBarcodeQuality()

def getBarcodeQuality

(

self

)

Mode which enables methods to recognize barcode elements with the selected quality.

Barcode element with lower quality requires more hard methods which slows the recognition. :

Parameters

self	Mode which enables methods to recognize barcode elements with the selected quality.

getComplexBackground()

def getComplexBackground

(

self

)

Mode which enables or disables additional recognition of color barcodes on color images.

:#return: Additional recognition of color barcodes on color images.

getDeconvolution()

def getDeconvolution

(

self

)

Deconvolution (image restorations) mode which defines level of image degradation.

Originally deconvolution is a function which can restore image degraded (convoluted) by any natural function like blur, during obtaining image by camera. Because we cannot detect image function which corrupt the image, we have to check most well know functions like sharp or mathematical morphology. :

Returns

: Deconvolution mode which defines level of image degradation.

getHighPerformance()

def getHighPerformance ( )

static

HighPerformance recognition quality preset.

High quality barcodes are recognized well in this mode.

     reader = Recognition.BarCodeReader("test.png")
     reader.setQualitySettings(QualitySettings.getHighPerformance())
\ebdcode
@return HighPerformance recognition quality preset.

getHighQuality()

def getHighQuality ( )

static

HighQuality recognition quality preset.

This preset is developed for low quality barcodes.

reader = Recognition.BarCodeReader("test.png")
reader.setQualitySettings(QualitySettings.getHighQuality())

Returns

HighQuality recognition quality preset.

getHighQualityDetection()

def getHighQualityDetection ( )

static

HighQualityDetection recognition quality preset.

Same as NormalQuality but with high quality DetectorSettings

reader = Recognition.BarCodeReader("test.png")
reader.setQualitySettings(QualitySettings.getHighQualityDetection())

Returns

HighQualityDetection recognition quality preset.

getInverseImage()

def getInverseImage

(

self

)

:

Returns

: Additional recognition of barcodes on images with inverse colors

getMaxQualityDetection()

def getMaxQualityDetection ( )

static

MaxQualityDetection recognition quality preset.

Same as NormalQuality but with highest quality DetectorSettings. Allows to detect diagonal and damaged barcodes.

reader = Recognition.BarCodeReader("test.png")
reader.setQualitySettings(QualitySettings.getMaxQualityDetection())

Returns

MaxQualityDetection recognition quality preset.

getMinimalXDimension()

def getMinimalXDimension

(

self

)

Minimal size of XDimension in pixels which is used with UseMinimalXDimension.

:

Returns

: Minimal size of XDimension in pixels which is used with UseMinimalXDimension.

getNormalQuality()

def getNormalQuality ( )

static

NormalQuality recognition quality preset.

Suitable for the most of barcodes

reader = Recognition.BarCodeReader("test.png")
reader.setQualitySettings(QualitySettings.getNormalQuality())

Returns

NormalQuality recognition quality preset.

getXDimension()

def getXDimension

(

self

)

Recognition mode which sets size (from 1 to infinity) of barcode minimal element: matrix cell or bar.

:

Returns

: size (from 1 to infinity) of barcode minimal element: matrix cell or bar.
