Class QRCodeEncoder

java.lang.Object

org.opencv.objdetect.QRCodeEncoder

public class QRCodeEncoder
extends java.lang.Object

Groups the object candidate rectangles. rectList Input/output vector of rectangles. Output vector includes retained and grouped rectangles. (The Python list is not modified in place.) weights Input/output vector of weights of rectangles. Output vector includes weights of retained and grouped rectangles. (The Python list is not modified in place.) groupThreshold Minimum possible number of rectangles minus 1. The threshold is used in a group of rectangles to retain it. eps Relative difference between sides of the rectangles to merge them into a group.

Method Detail

__fromPtr__

public static QRCodeEncoder __fromPtr__(long addr)

create

public static QRCodeEncoder create()

Constructor

Returns:

automatically generated

create

public static QRCodeEncoder create(QRCodeEncoder_Params parameters)

Constructor

Parameters:

parameters - QR code encoder parameters QRCodeEncoder::Params

Returns:

automatically generated

encode

public void encode(java.lang.String encoded_info,
                   Mat qrcode)

Generates QR code from input string.

Parameters:

encoded_info - Input string to encode.

qrcode - Generated QR code.

encodeStructuredAppend

public void encodeStructuredAppend(java.lang.String encoded_info,
                                   java.util.List<Mat> qrcodes)

Generates QR code from input string in Structured Append mode. The encoded message is splitting over a number of QR codes.

Parameters:

encoded_info - Input string to encode.

qrcodes - Vector of generated QR codes.
