boofcv.alg.fiducial.aztec.AztecFinderPatternDetector<T>

All Implemented Interfaces:

VerbosePrint

public class AztecFinderPatternDetector<T extends ImageGray<T>>
extends SquareLocatorPatternDetectorBase<T>

Searches for Aztec finder patterns inside an image and returns a list of candidates. Finder patterns are found by looking at the external contour of block quadrilaterals and looking for quadrilaterals that have a similar center pixel. If one, two, or three match then that's consider a match for compact or full-range Aztec codes.
