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

public class QrCodeAlignmentPatternLocator<T extends ImageGray<T>>
extends Object

Searches the image for alignment patterns. First it computes a transform that removes perspective distortion using previously detected position patterns. Then it searches inside the image for the position patterns. If available, adjacent position patterns are used to adjust the search so that locations distant from position patterns can be compensated for. NOTE: The current algorithm is a bit brittle and is a good target for further improvement. It has issues converging when its initial guess is off.
