新版新增中文水印出错

水印为“中文测试test”没问题，
但是水印为“中文测试TEST”就会报错了
java.lang.RuntimeException: OpenCV(3.4.2) /Users/travis/build/bytedeco/javacpp-presets/opencv/cppbuild/macosx-x86_64/opencv-3.4.2/modules/core/src/arithm.cpp:659: error: (-209:Sizes of input arguments do not match) The operation is neither 'array op array' (where arrays have the same size and the same number of channels), nor 'array op scalar', nor 'scalar op array' in function 'arithm_op'

是不是不支持中文？我电脑上中文被替换成了 “？”

不需要原图解码的水印才叫“盲水印”吧？
你这个文本类型的是盲水印，图像类型的好像不算盲水印了？
以上拙见如有不当请指摘。

1、首先我改encode的代码 是因为你的代码dft的文字盲水印耗时需要3s 以上,我加了些优化的代码

` public void encode(String image, String watermark, String output) {
// Mat src = Utils.read(image, CV_8S);
//
// List channel = new ArrayList<>(3);
// List newChannel = new ArrayList<>(3);
// split(src, channel);
//
// for (int i = 0; i < 3; i++) {
// Mat com = this.converter.start(channel.get(i)).clone();
// this.addWatermark(com, watermark);
// this.converter.inverse(com);
// newChannel.add(i, com);
// }
//
// Mat res = new Mat();
// merge(newChannel, res);
//
// if (res.rows() != src.rows() || res.cols() != src.cols()) {
// res = new Mat(res, new Rect(0, 0, src.width(), src.height()));
// }
//
// imwrite(output, res);

    Mat src = Utils.read(image, CV_8S);
    Mat res = new Mat();
    Mat padded = splitSrc(src);
    planes.add(padded);
    planes.add(1, Mat.zeros(padded.size(), CV_32F));
    merge(planes, res);
    dft(res, res);
    Scalar s = new Scalar(0, 0, 0, 0);
    Point p = new Point(res.cols() / 3, res.rows() / 3);
    putText(res, watermark, p, FONT_HERSHEY_COMPLEX, 1.0, s, 3,
            8, false);
    flip(res, res, -1);
    putText(res, watermark, p, FONT_HERSHEY_COMPLEX, 1.0, s, 3,
            8, false);
    flip(res, res, -1);

    Mat invDFT = new Mat();
    idft(res, invDFT, Core.DFT_SCALE | Core.DFT_REAL_OUTPUT, 0);
    Mat restoredImage = new Mat();
    invDFT.convertTo(restoredImage, 0);
    if (allPlanes.size() == 0) {
        allPlanes.add(restoredImage);
    } else {
        allPlanes.add(0, restoredImage);
    }
    Mat lastImage = new Mat();
    merge(allPlanes, lastImage);
    imwrite(output, lastImage);
}`

2、运行的时候报错
Exception in thread "main" CvException [org.opencv.core.CvException: cv::Exception: OpenCV(4.1.2) /Users/travis/build/bytedeco/javacpp-presets/opencv/cppbuild/macosx-x86_64/opencv-4.1.2/modules/core/src/merge.dispatch.cpp:129: error: (-215:Assertion failed) mv[i].size == mv[0].size && mv[i].depth() == depth in function 'merge' ] at org.opencv.core.Core.merge_0(Native Method) at org.opencv.core.Core.merge(Core.java:4067) at com.example.demo.converter.DftConverter.merge11(DftConverter.java:109) at com.example.demo.dencoder.Encoder.encode(Encoder.java:83) at com.example.demo.BlindWatermark.main(BlindWatermark.java:53)

3、如果我还原成你的就可以正常执行 ，所以我想问下 ，为什么我基于你的类库改的 ，为什么我运行不起来呢 ？

`

麻烦大佬看看谢谢

你好，"测试test"解码出来是"口口test"
中文解码出来是两个竖直的长方形

解水印不能解析出文字吗？

我执行java命令时增加的参数 -Djava.library.path=D:/app/opencv/java/x64
我的dll文件都这这个目录

  public static void main(String[] args) {
    SpringApplication.run(BlindWatermarkApplication.class, args);
    System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    loadOpenCvTest();
    Loader.load(opencv_core.class);
  }

  public static void loadOpenCvTest() {
    Mat mat = Mat.eye(3, 3, CvType.CV_8UC1);
    logger.info("opencv load success ! \n" + mat.dump());
  }

这是我的java代码，第一种方式的测试可以通过，但是运行到load方法就报错，请问时什么原因？

使用离散傅里叶变换编码过程中没有任何错误提示，执行完毕后会输出一张正常图片，图片体积略有增加，但是解码导出的图片中并没有得到正确结果（只有雪花）。
经测试
BlindWatermark-v0.0.3-windows-x86_64.jar
BlindWatermark-v0.0.3-windows-x86_64-gpu.jar
均出现相同情况，其他系统版本未测试。

使用离散余弦变换则可以正常编解码，没有出现问题。
