OpenCV Assertion Failed for Perspective Transform.

For this code 

    Mat hg = Calib3d.findHomography(obj, scene, 8, 10);

    Mat obj_corners = new Mat(4,1,CvType.CV_32FC1);
    Mat scene_corners = new Mat(4,1,CvType.CV_32FC1);

    Core.perspectiveTransform(obj_corners, scene_corners, hg);

This is the error, also tried changing the type to CV_8UC1, CV_32F and CV_32FC1

When I use log for the two I get

What am I missing here?
