GMSD and SSIM Quality Metrics

WorBry · 13th February 2019, 21:31

I've been running some quality metric tests with VMAF and FFMPEG SSIM and PSNR.

https://forum.doom9.org/showthread.p...70#post1864770

While I still have the test files I'd like to see how the SSIM and GMSD metrics (in muvsfunc) compare.

The function descriptions state:

SSIM - 'The mean SSIM (MSSIM) index value of the distorted image will be stored as frame property 'PlaneSSIM' in the output clip'.

GMSD - 'The distortion degree of the distorted image will be stored as frame property 'PlaneGMSD' in the output clip. The value of GMSD reflects the range of distortion severities in an image.'

But I'm not clear how to access these results.
