Watson Visual Recognition API 文本到字符串

Question

我知道这可能是一个愚蠢的问题，但我很难将识别文本中的视觉识别转换为我可以使用和操作的字符串。

这是在 Java 中。

有人可以帮忙吗？这可能与挖掘方法并找到正确的组合有关......

package com.mycompany.app;

import com.ibm.watson.developer_cloud.visual_recognition.v3.VisualRecognition;

import com.ibm.watson.developer_cloud.visual_recognition.v3.model.*;

import java.io.File;
import java.util.concurrent.ExecutionException;
public class App 
{
public static void main( String[] args ) throws ExecutionException, InterruptedException {
    VisualRecognition service = new VisualRecognition(VisualRecognition.VERSION_DATE_2016_05_20);
    service.setApiKey("a46d79a8aa20ed4b1ad3bc25a449c15d212d5db7");

    ClassifierOptions p  = new ClassifierOptions.Builder().classifierName("letters").addClass("H", new File("src/pictures/CapitalH.zip")).addClass("h", new File("src/pictures/LowercaseH.zip")).build();

    File f1 = new File("src/pictures/CapitalH.zip");
    File f2 = new File("src/pictures/LowercaseH.zip");
    File f3 = new File("src/pictures/HiM.zip");

    //VisualClassifier c1 = service.createClassifier("H", f1, f2);
    //service.createClassifier(p).execute();
    //VisualClassifier c1 = new VisualClassifier();
    //VisualClass cc1 = (VisualClass) service.createClassifier(p);

    service.createClassifier(p);
    VisualRecognitionOptions ops; //find out how to add classifications for letters to this, then add this to visualClassification

    ClassifyImagesOptions pp = new ClassifyImagesOptions.Builder().images(f3).classifierIds("H").build();

    ClassifyImagesOptions ppp = new ClassifyImagesOptions.Builder().images(f3).build();

    VisualClassification result = service.classify(pp).execute();

    VisualRecognitionOptions now = new VisualRecognitionOptions.Builder().images(f3).build();
    //System.out.println(service.recognizeText(now).execute());

    //System.out.println(service.recognizeText(now));

    RecognizedText t = service.recognizeText(now).execute();
    t = service.recognizeText(now).rx().join();
    String s = service.recognizeText(now).rx().toString();

    //System.out.println(service.getClassifiers());
    //System.out.println(result);



    }
}

在这一行之后，尝试打印出t:

RecognizedText t = service.recognizeText(now).execute();

您应该会在格式化的 JSON 对象中看到文本。
