Question

这是我的java类，我从中调用了我的c ++代码，我在c ++中编写了opencv函数代码

    InputStream is;
    is = this.getResources().openRawResource(R.drawable.foot);
    Bitmap bmInImg = BitmapFactory.decodeStream(is);

    int [] mPhotoIntArray;
    int [] mCannyOutArray;

    mPhotoIntArray = new int[bmInImg.getWidth() * bmInImg.getHeight()];
    // Copy pixel data from the Bitmap into the 'intArray' array
    bmInImg.getPixels(mPhotoIntArray, 0, bmInImg.getWidth(), 0, 0, bmInImg.getWidth(), bmInImg.getHeight());

    //create the Brightness result buffer
    mCannyOutArray = new int[bmInImg.getWidth() * bmInImg.getHeight()];

    //
    // Do Brightness
    //
    BrightnessJNI(bmInImg.getHeight(), bmInImg.getWidth(), mPhotoIntArray, mCannyOutArray);

    //
    // Convert the result to Bitmap
    //
    Bitmap bmOutImg = Bitmap.createBitmap(bmInImg.getWidth(), bmInImg.getHeight(), Config.ARGB_8888);  
    bmOutImg.setPixels(mCannyOutArray, 0, bmInImg.getWidth(), 0, 0, bmInImg.getWidth(), bmInImg.getHeight());


    imageview_2.setImageBitmap(bmOutImg);

    //
    // Save the result to file
    //
    String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
    String outFileName = extStorageDirectory + "/Brightness";

    OutputBitmapToFile(bmOutImg, outFileName);





}

void OutputBitmapToFile(Bitmap InBm, String Filename)
{
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    InBm.compress(Bitmap.CompressFormat.PNG, 100, bytes);

    File f = new File(Filename);
    try
    {
        f.createNewFile();
        //write the bytes in file
        FileOutputStream fo = new FileOutputStream(f);
        fo.write(bytes.toByteArray());
    } 
    catch (Exception e) 
    {
        e.printStackTrace();
    }           
}

这是我的用于histrogram均衡的opencv函数代码

       jint* _in = env->GetIntArrayElements(in, 0);
       jint* _out = env->GetIntArrayElements(out, 0);


    //Build the Mat structure for input data
    Mat mSrc(height, width, CV_8UC4, (unsigned char *)_in);
    //Build the Mat structure for output data
    Mat mOut(height, width, CV_8UC4, (unsigned char *)_out);

    //Convert Mat to IplImage
    IplImage mSrcImg = mSrc;
    IplImage mOutImg = mOut;
    vector<IplImage*> b , g ,r;
    cvSplit(&mSrcImg , &b , &g , &r , NULL);
    cvEqualizeHist(&b, &b);
    cvEqualizeHist(&g, &g);
    cvEqualizeHist(&r, &r);
    cvMerge(&b, &g, &r, NULL, &mOutImg );

因为我在这里使用C界面，所以我假设我在C代码

中做错了

错误

我的设备上也显示错误，错误消息运行然后突然打开应用程序然后关闭

得到错误的参数错误
