OpenCV C语音代码转Java代码问题

[逸笙]

做OpenCV的证件照换背景问题，需要C语言代码转成java代码，但是c语言不是很熟悉，有些语法不知道什么意思，求解：

如图下面那个红框框的C代码用java应该怎么写呢，求指点，万分感谢大家。

Mat hsv_hl, hsv_hh, hsv_s, hsv_v, color;
    threshold(hsv_channels[0], hsv_hl, 100, 255, 0);
    threshold(hsv_channels[0], hsv_hh, 119, 255, 1);
    threshold(hsv_channels[1], hsv_s, 43, 255, 0);
    threshold(hsv_channels[2], hsv_v, 80, 255, 0);

    threshold(gray, bin, 100, 255, CV_THRESH_OTSU);
    //imshow("bin", bin);
    color = hsv_hl & hsv_hh & hsv_s & bin;

 Mat hsv_hl = null, hsv_hh = null, hsv_s = null, hsv_v = null, color = null;
        Imgproc.threshold(hsv_channels.get(0), hsv_hl, 100, 255, 0);
        Imgproc.threshold(hsv_channels.get(0), hsv_hh, 119, 255, 1);
        Imgproc.threshold(hsv_channels.get(1), hsv_s, 43, 255, 0);
        Imgproc.threshold(hsv_channels.get(2), hsv_v, 80, 255, 0);

        Imgproc.threshold(gray, bin, 100, 255, Imgproc.THRESH_OTSU);
        //C如下
//        color = hsv_hl & hsv_hh & hsv_s & bin;
        //java ?应该怎么写呢
