ColorDetecting with opencv 3.4.1

edit savecancel

I can't find where is the error ! My code :

public static void main(String[] args) {
    System.load("C:\\Users\\MustaProd\\Desktop\\opencv\\build\\java\\x64\\opencv_java341.dll");

    Mat img;
    img = imread("../feu/feu.png",1);

    Mat outRED = new Mat();
    Mat outOrange = new Mat();
    Mat outGREEN = new Mat();

    //BGR

    //obtenir RED
    Scalar redDebut = new Scalar(28,28,112);
    Scalar redFin = new Scalar(28,28,112);
    inRange(img,redDebut,redFin,outRED);

    //obtenir Orange
    inRange(img,new Scalar(0,85,204),new Scalar(206,231,247),outOrange);

    //obtenir GREEN
    inRange(img,new Scalar(0,128,0),new Scalar(93,236,178),outGREEN);


    int r = Core.countNonZero(outRED);
    int o = Core.countNonZero(outOrange);
    int g = Core.countNonZero(outGREEN);

    if(r>o && r>g) {
        System.out.println("Feu rouge!!!");
    }
    else if(o>g && o>r){
        System.out.println("Feu Orange!!!");
    }
    else {
        System.out.println("Feu Vert");
    }


}

output :
