QrCodePreciseDetector

public QrCodePreciseDetector(InputToBinary<T> inputToBinary,
QrCodePositionPatternDetector<T> detectPositionPatterns,
@Nullable
@Nullable String defaultEncoding,
boolean copyBinary,
Class<T> imageType)

Method Details

process

public void process(T gray)

Description copied from interface: QrCodeDetector

Processes the image and searches for fiducials

Specified by:

process in interface QrCodeDetector<T extends ImageGray<T>>

Parameters:

gray - The image being processed

getDetections

public List<QrCode> getDetections()

Description copied from interface: QrCodeDetector

List of detected fiducials

Specified by:

getDetections in interface QrCodeDetector<T extends ImageGray<T>>

Returns:

List of detected QR-Codes. WARNING: Data might be recycled on next call to QrCodeDetector.process(T)

getFailures

public List<QrCode> getFailures()

Description copied from interface: QrCodeDetector

List of likely fiducials that were rejected.

Specified by:

getFailures in interface QrCodeDetector<T extends ImageGray<T>>

Returns:

List of rejected candidate QR-Codes. WARNING: Data might be recycled on next call to QrCodeDetector.process(T)

setLensDistortion

public void setLensDistortion(int width,
int height,
@Nullable
@Nullable LensDistortionNarrowFOV model)

Specifies transforms which can be used to change coordinates from distorted to undistorted and the opposite coordinates. The undistorted image is never explicitly created.

Parameters:

width - Input image width. Used in sanity check only.

height - Input image height. Used in sanity check only.

model - distortion model. Null to remove a distortion model.

getBinary

public GrayU8 getBinary()

setProfilerState

public void setProfilerState(boolean active)

resetRuntimeProfiling

public void resetRuntimeProfiling()

getSquareDetector

public DetectPolygonBinaryGrayRefine<T> getSquareDetector()

getImageType

public Class<T> getImageType()

Description copied from interface: QrCodeDetector

Type of image it can process

Specified by:

getImageType in interface QrCodeDetector<T extends ImageGray<T>>

Returns:

input image type
