Hi forum,

Im trying to use perspectiveTransform but I keep getting error. I tried to follow the solution from this thread http://answers.opencv.org/question/18252/opencv-assertion-failed-for-perspective-transform/

_players[i].getCoordinates() is of type Point

_homography_matrix is a 3 x 3 Mat

    Mat temp_Mat = Mat::zeros(2, 1, CV_32FC2);

    for (int i = 0; i < _players.size(); i++)
    {
        cout << Mat(_players[i].get_Coordinates()) << endl;
        perspectiveTransform(Mat(_players[i].get_Coordinates()), temp_Mat, _homography_matrix);
    }

Also, how do I convert temp_Mat into type Point ?

I have tried checking for the types my Mat using the link below.

Still no success.
