如何使用opencv在android java中获取带有统计信息的connectedComponents，以及如何使用这些统计信息来获取左点、右品脱、质心、面积等

import org.opencv.android.OpenCVLoader;

// 在Activity的onCreate方法中调用
if (!OpenCVLoader.initDebug()) {
    OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_3_4_0, this, mLoaderCallback);
}

// 在Activity中添加LoaderCallback回调
private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
    @Override
    public void onManagerConnected(int status) {
        switch (status) {
            case LoaderCallbackInterface.SUCCESS:
                // OpenCV加载成功，可以进行相关操作
                break;
            default:
                super.onManagerConnected(status);
                break;
        }
    }
};
