如何在Android的TessBaseApi中设置textord_equation_detect为true

Question

我在build.gradle中添加了tess-two库，如下所示

        implementation 'com.rmtheis:tess-two:9.1.0'

我想用TessBaseApi()来识别数学表达式和符号，所以我需要设置真的textord_equation_detect，但我不知道如何做我用TessBaseApi写的this.The代码，如下所示

    public static boolean init(AssetManager assetManager){
    mTess = new TessBaseAPI();
    String datapath = CommonUtils.APP_PATH;
    File dir =new File(datapath + "tessdata/");
    if(!dir.exists()) {
        dir.mkdir();
        try {
            InputStream inStream = assetManager.open("CSDL/eng.traineddata");

            FileOutputStream outStream = new FileOutputStream(datapath + "tessdata/eng.traineddata");

            byte[] buffer = new byte[1024];
            int readCount = 0;
            while (((readCount = inStream.read(buffer)) != -1)) {
                outStream.write(buffer, 0, readCount);

            }
            outStream.flush();
            outStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    mTess.init(datapath,"eng");
    return true;
}

如何设置真正的textord_equation_detect？你能帮帮我吗？

Answer 1

mTess.SetVariable("textord_equation_detect", "T");
