    void Blending::Blend(int, void*)
    {
        alpha = (double)defaultvalue / 100;
        addWeighted(img, alpha, img2, 1.0 - alpha, 0, des);
        imshow("Blendimage", des);
    }



       int main()
    {
    Blending ble;

    ble.Blend(defaultvalue, 0);

    createTrackbar("Blend", "Blendimage", &defaultvalue,maximumvalue,ble.Blend);
    waitKey(0);
