Objective metrics

Is there a script in the repository which can give objective metrics such as PSNR, SSIM. For example, using ffmpeg, we can remove alternate frames from a video stream. And then interpolate using Super-SloMo. After that we can calculate the PSNR/SSIM of the interpolated frames with respect to the original ground truth frames. This way, if there are other interpolation methods, the PSNR/SSIM can be compared for different algorithms.

I saw some PSNR numbers on UCF-101 dataset but am not sure if those numbers mean something similar.
