没有范围的图片

Question

我正在取出画廊图像，并对其进行了一定范围的处理，然后又将图像返回到imageview中，但是我想要的是，当图像超出范围时，它将向我发送消息。

public void processImage(){
    String[] partes=vector.toString().split("external_files/");
    String part=partes[1];
    String dato = "/" + part;

    try{
        Mat img = imread(Environment.getExternalStorageDirectory().getAbsolutePath() + dato);
        Mat oImg = detectColor(img);

        // converting image from Mat to bitmap to display in ImageView:
        Bitmap bm = Bitmap.createBitmap(oImg.cols(), oImg.rows(),Bitmap.Config.ARGB_8888);
        Utils.matToBitmap(oImg,bm);
        imgView.setImageBitmap(bm);

        Bitmap bitmap=((BitmapDrawable)imgView.getDrawable()).getBitmap();

    }catch (Exception xs){
        Log.v(TAG,"no maduro" + xs.getMessage());
        texto.setText("no maduro");
        leer1();
    }
}


Mat detectColor(Mat srcImg) {
    Mat blurImg = new Mat();
    Mat hsvImage = new Mat();
    Mat color_range = new Mat();
    Mat sin_rango =new Mat();

    //bluring image to filter small noises.
    Imgproc.GaussianBlur(srcImg, blurImg, new Size(5,5),0);

    //converting blured image from BGR to HSV
    Imgproc.cvtColor(blurImg, hsvImage, Imgproc.COLOR_BGR2HSV);

    //filtering pixels based on given HSV color range
    Core.inRange(hsvImage, new Scalar(0,50,50), new Scalar(5,255,255), color_range);
    return color_range;

}
