hybrid imaging

[jax666999]

[output]I've put together this program to make a hybrid image from two given images. It scales them corectly and puts them together but they dont quite line up properly
I've been scouring it for a few hours trying to findsome kind of miscalculation and making minor tweeks. I cant find any thing I need fresh eyes on this

double theta1 = atan2((double)(p12.y - p11.y),(double)(p12.x - p11.x));
      double theta2 = atan2((double)(p22.y - p21.y),(double)(p22.x - p21.x));

	double thetad = theta2 - theta1;
	Point center = Point(aligned_img2.cols/2, aligned_img2.rows/2);


	Mat Rot_mat = getRotationMatrix2D(center, thetad * 180/3.1415926535898, 1.0);

	warpAffine(aligned_img2, img2, Rot_mat, aligned_img2.size());
	img2.copyTo(aligned_img2);

this is the code segment that rotates the second image to aline the two can anyone see what is wrong here tell me if you need to see more code.
