Package boofcv.alg.fiducial.aztec

Class AztecDecoderImage<T extends ImageGray<T>>

java.lang.Object

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

All Implemented Interfaces:

VerbosePrint

public class AztecDecoderImage<T extends ImageGray<T>>
extends Object
implements VerbosePrint

Given location of a candidate finder patterns and the source image, decode the marker. Note: A fixed feature is a feature on the marker which is not dynamically computed. E.g. the pyramid.

Method Details

process

public boolean process(AztecPyramid locatorPattern,
 T gray,
 AztecCode marker)

Attempts to decode a marker at the specified location of a previously found locator pattern

Parameters:

locatorPattern - (Input) Coordinates of locator pattern

gray - (Input) Gray scale image of marker

marker - (Output) storage for decoded marker

Returns:

true if the marker could be decoded

decodeMode

protected boolean decodeMode(AztecPyramid locator,
 AztecCode marker)

Reads the image and decodes the marker's mode

Parameters:

locator - Locator pattern

marker - Storage for decoded marker

Returns:

true if successful or false if it failed

decodeMessage

protected boolean decodeMessage(AztecCode marker)

Reads the message data from the image then decodes it. Results are stored in Marker
