ImageMagick does not return an MTF but you can get other types of metrics with the compare program. It returns AE, MAE, MSE, PAE, PSNR, or RMSE.

Ok, here's the code we use for gaussian blur:
  • alpha=exp(-((double) u*u+v*v)/(2.0*sigma*sigma));
    kernel=(double) (alpha/(2.0*MagickPI*sigma*sigma));
The kernel width is 2 * radius +1.
