Class QrCodePositionPatternDetector<T extends boofcv.struct.image.ImageGray<T>>

java.lang.Object

boofcv.alg.fiducial.qrcode.QrCodePositionPatternDetector<T>

public class QrCodePositionPatternDetector<T extends boofcv.struct.image.ImageGray<T>>
extends java.lang.Object

Detects position patterns for a QR code inside an image and forms a graph of ones which can potentially be connected together. Squares are detected in the image and position patterns are found based on their appearance.
