请问一下，你知道用zxing在MATLAB中识别二维码

我用zxing.dll制作了二维码，但不知道怎么识别，能给代码吗

Answer 1

试试吧!

function test1
    zxingpath = fullfile(fileparts(mfilename('fullpath')), 'zxing.jar');
    javaaddpath(zxingpath);
    I = imread('barcode.jpg');
    imshow(I);
    codestr = zxing_decode(I);
    text(100,100,codestr,'FontSize',20,'Color','r');
end

function ret = zxing_decode(im)
    import com.google.zxing.*
    im = im2java(im);
    width = im.getWidth(); 
    height = im.getHeight();

    source = client.j2se.BufferedImageLuminanceSource(im.getBufferedImage());
    binarizer = common.HybridBinarizer(source);
    bitmap = BinaryBitmap(binarizer);
    reader = MultiFormatReader();
    ret = char(reader.decode(bitmap));
end

追问

Undefined variable "client" or class "client.j2se.BufferedImageLuminanceSource".
source = client.j2se.BufferedImageLuminanceSource(im.getBufferedImage());
能不能给我你的zxing.jar
