在openCV中获取色调值以进行颜色识别

Question

我将rgb图像转换为hsv

我使用函数inRange（）来检测图像中的红色

现在我想识别颜色而不是检测： - 我想将色调值与红色范围进行比较..如果它位于其中...打印红色 否则如果它在蓝色范围内说蓝色......那么

如果比较Mat hue，如果它在100到180之间

int main()
{

Mat image;
image = imread("C:/Users/Maram/Documents/Visual Studio 2013/Projects/firsttrialw310/x64/Debug/carcolor.png", CV_LOAD_IMAGE_COLOR);

if (!image.data)
{
    cout << "Could not open or find the image" << std::endl;
    return -1;
}

// Create a new matrix to hold the HSV image
Mat HSV;

// convert RGB image to HSV
cvtColor(image, HSV, CV_RGB2HSV);

namedWindow("Display window", CV_WINDOW_AUTOSIZE);
imshow("Display window", image);

namedWindow("Result window", CV_WINDOW_AUTOSIZE);
imshow("Result window", HSV);


vector<Mat> hsv_planes;
split(HSV, hsv_planes);
Mat h = hsv_planes[0]; // H channel
Mat s = hsv_planes[1]; // S channel
Mat v = hsv_planes[2]; // V channel

namedWindow("hue", CV_WINDOW_AUTOSIZE);
imshow("hue", h);
namedWindow("saturation", CV_WINDOW_AUTOSIZE);
imshow("saturation", s);
namedWindow("value", CV_WINDOW_AUTOSIZE);
imshow("value", v);



//// red color range
Scalar hsv_l(100, 150, 150);
Scalar hsv_h(180, 255, 255);
Mat bw;
inRange(HSV, hsv_l, hsv_h, bw);
imshow("Specific Colour", bw);
////

//black cv::Scalar(0, 0, 0, 0), cv::Scalar(180, 255, 40, 0)
//white cv::Scalar(0, 0, 80, 0), cv::Scalar(180, 255, 255, 0)
