java - EXCEPTION_ACCESS_VIOLATION (0xc0000005) --javaCV

Question

我正在开发一个在 javacv 中实现 BOW 模型的应用程序。

原代码是用c++写的

头等舱：

public class BOW {

  final String trainingData ="";
  final String testData="";

  int dictionarySize = 500;

  // TermCriteria tc(CV_TERMCRIT_ITER, 10, 0.001);

  int retries = 1;

  int flags = CV_KMEANS_USE_INITIAL_LABELS;

  CvTermCriteria termcrit ;

  BOWKMeansTrainer bMeansTrainer ;

  BOWImgDescriptorExtractor bDescriptorExtractor;

  FeatureDetector featureDetector;

  DescriptorExtractor descriptorExtractor;

  DescriptorMatcher descriptorMatcher;

public BOWKMeansTrainer getbMeansTrainer() {
    return bMeansTrainer;
}


public void setbMeansTrainer(BOWKMeansTrainer bMeansTrainer) {
    this.bMeansTrainer = bMeansTrainer;
}


public BOWImgDescriptorExtractor getbDescriptorExtractor() {
    return bDescriptorExtractor;
}


public void setbDescriptorExtractor(
        BOWImgDescriptorExtractor bDescriptorExtractor) {
    this.bDescriptorExtractor = bDescriptorExtractor;
}


public FeatureDetector getFeatureDetector() {
    return featureDetector;
}


public void setFeatureDetector(FeatureDetector featureDetector) {
    this.featureDetector = featureDetector;
}


public DescriptorExtractor getDescriptorExtractor() {
    return descriptorExtractor;
}


public void setDescriptorExtractor(DescriptorExtractor descriptorExtractor) {
    this.descriptorExtractor = descriptorExtractor;
}


public DescriptorMatcher getDescriptorMatcher() {
    return descriptorMatcher;
}


public void setDescriptorMatcher(DescriptorMatcher descriptorMatcher) {
    this.descriptorMatcher = descriptorMatcher;
}


public BOW() {
    super();
    try {
        featureDetector = FeatureDetector.create("SIFT");
    descriptorExtractor=DescriptorExtractor.create("SIFT");
    descriptorMatcher= DescriptorMatcher.create("FlannBased");
    termcrit = new CvTermCriteria(CV_TERMCRIT_ITER, 10, 0.001);
    bMeansTrainer = new BOWKMeansTrainer(dictionarySize, termcrit , retries, flags);
    bDescriptorExtractor = new BOWImgDescriptorExtractor( descriptorExtractor, descriptorMatcher);

    } catch (Exception e) {

        e.getStackTrace();
    }

}



 public void extractTrainingVocabulary (String  baseurl ) 
  {
    File dir = new File(baseurl);

    for (File child : dir.listFiles())

        }

        else 
        {

                 final CvMat image = cvLoadImageM(child.getName());
                 if (!image.empty())
                 {

                    KeyPoint keypoints = new KeyPoint(); // a verifier 
                    featureDetector.detect(image, keypoints, null);

                    if (keypoints.isNull())
                    {
                        System.out.println("Warning: Could not find key points in image: "+

                        descriptorExtractor.compute(image, keypoints, featurs);


                        bMeansTrainer.add(featurs);
                    }
                 }

                 else

                 }


            }
        }
    }
  }

public void extractBOWDescriptor (String baseurl , CvMat descriptors ) 

  {
    File dir = new File(baseurl);

    for (File child : dir.listFiles())
    {

            extractBOWDescriptor(child.getName(), descriptors);

                 final CvMat image = cvLoadImageM(child.getName());

                 if (!image.empty())
                 {

                    KeyPoint keypoints = new KeyPoint(); // a verifier 
                    featureDetector.detect(image, keypoints, null);

                    if (keypoints.isNull())
                    {
                        System.out.println("Warning: Could not find key points in image: "+

                                child.getName()
                                );
                    }

                    else 
                    {
                        CvMat BoWdescriptors = new CvMat() ; // 
                        bDescriptorExtractor.compute(image, keypoints, BoWdescriptors, null, null);

                        descriptors.put(descriptors);
                   //     float label=Float.parseFloat(child.getName());
                    //  labels.put(label);

                 }

            }
        }
    }

  }

}

主类：

  package pack;


public class Main {

/**
 * @param args
 */
public static void main(String[] args) {
     System.out.println("ppppppp");

    String trainingDatapath="bowdemo\\data\\train";
    String evalDatapath="bowdemo\\data\\evam";
    BOW bow = null;

    try {
                 bow = new BOW();
    } 

    catch (Exception e) {

        e.getStackTrace();
    }

    bow.extractTrainingVocabulary(trainingDatapath);

//   MatVector descriptos = bow.getbMeansTrainer().getDescriptors();

    CvMat dictionnary  = bow.getbMeansTrainer().cluster();

    bow.getbDescriptorExtractor().setVocabulary(dictionnary);


    CvMat evalData = new CvMat(bow.dictionarySize);

    bow.extractBOWDescriptor(evalDatapath, evalData);


}

}
