Question

我在我的应用程序中使用Mobile Vision API进行人脸检测到目前为止我已经成功完成了这项工作。它适用于我第一次运行应用程序时设置的特定图像，但之后...我试图替换不同的图像进行面部检测，它给出了错误java.lang.OutOfMemoryError

以下是我的代码

SELECT CONVERT(Datetime, '2015-10-29 15:01:00', 120)

这是我的logcat

      Bitmap myBitmap;
      FaceDetector detector;
      @Override
      protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
           //Load An Image////
      BitmapFactory.Options options = new BitmapFactory.Options();
      options.inMutable=true;
       Bitmap b =  = BitmapFactory.decodeResource(
       getApplicationContext().getResources(),
       R.drawable.image,options);
        myBitmap = b.copy(Bitmap.Config.RGB_565, true);
        b.recycle();
        ////////////////
        detector = new FaceDetector.Builder(getApplicationContext())
        .setTrackingEnabled(false)
         .setLandmarkType(FaceDetector.ALL_LANDMARKS)
            .build();
       if (!detector.isOperational())
              {    Toast.makeText(MainActivity.this, "NO face deteted."Toast.LENGTH_SHORT)
          .show();} 
            else {
          Frame frame = new  Frame.Builder().setBitmap(myBitmap).build();
                  SparseArray<com.google.android.gms.vision.face.Face> faces =                    detector.detect(frame);
                 FaceView faceView = (FaceView) findViewById(R.id.faceView);
                 faceView.setContent(myBitmap, faces);
       }

......需要你的帮助......

试试这个

Bitmap myBitmap;
FaceDetector detector;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //Load An Image////

    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inMutable=true;
    Bitmap b =  = BitmapFactory.decodeResource(
    getApplicationContext().getResources(),
    R.drawable.image,options);
    myBitmap = b.copy(Bitmap.Config.RGB_565, true);
    b.recycle();
    //////////////////
    detector = new FaceDetector.Builder(getApplicationContext())
            .setTrackingEnabled(false)
            .setLandmarkType(FaceDetector.ALL_LANDMARKS)
            .build();

    Detector<Face> safeDetector = new SafeFaceDetector(detector);

    Frame frame = new Frame.Builder().setBitmap(myBitmap).build();
    SparseArray<com.google.android.gms.vision.face.Face> faces = safeDetector.detect(frame);

    if (!safeDetector.isOperational()) {
        Toast.makeText(MainActivity.this, "NO face deteted."Toast.LENGTH_SHORT)
                .show();
    } else {

        FaceView faceView = (FaceView) findViewById(R.id.faceView);
        faceView.setContent(myBitmap, faces);

        safeDetector.release();
    }
}

for use facedetector release();必须在使用后调用。

和SafeDetector用法：面部检测器有小图像的bug，而safeDetector是该bug的补丁

在活动导入

添加此行

import com.google.android.gms.samples.vision.face.patch.SafeFaceDetector;

无法检测到面部检测Mobile Vision API的不同图像
