请清除我是Android和Java的新手 我使用了这段代码，但不知道这四个变量的含义 Imgproc.connectedComponentsWithStats(binarized,labeled,rectComponents,centComponents);

        Mat tmp = new Mat(bmp.getWidth(),bmp.getHeight(),CvType.CV_8U);

        Utils.bitmapToMat(bmp,tmp);

        Imgproc.cvtColor(tmp,tmp,Imgproc.COLOR_RGB2GRAY);

        Imgproc.threshold(tmp,40,255,Imgproc.THRESH_BINARY);

        Imgproc.GaussianBlur(tmp,new org.opencv.core.Size(5,5),0);

        Imgproc.threshold(tmp,130,Imgproc.THRESH_OTSU);

        Utils.matToBitmap(tmp,bmp);
        imageView.setImageBitmap(bmp);```

I want to get connected components with stats of tmp.
