Class QrCodeBinaryGridReader<T extends ImageGray<T>>

java.lang.Object
boofcv.alg.fiducial.qrcode.QrCodeBinaryGridReader<T>

public class QrCodeBinaryGridReader<T extends ImageGray<T>>
extends Object
Reads binary values from the qr code's grid. Top left corner of the qr code is it's origin. +x = right and +y = down same as it is in images.
