OpenCV：无法检测到白色物体

Question

能帮我解决检测白色或白色可见光的问题

    UByteIndexer srcIndexer = image.createIndexer();
    int[] hsv = new int[3];
    boolean yellow = false;
    for (int i = 0; i < srcIndexer.rows(); i++) {
        for (int j = 0; j < srcIndexer.cols(); j++) {
            if (j == x && i == y) {
                srcIndexer.get(i, j, hsv);
                if (hsv[0] <= 0 && hsv[1] <= 0 && hsv[2] >= 0 && hsv[2] <= 255) {
                    white = true;
                }
            }
        }
    }
    return white;
}

有人可以帮助我将白色的RGB转换为HSV吗？ 预先感谢，
