Adds a new Image Quality Assessment plugin. (16.75 KB, patch)

Description Mathieu Duponchelle 2015-06-22 13:48:26 UTC 
It only offers one metric for now, "dssim", available if
https://github.com/pornel/dssim was installed on the system
at the time the plugin was compiled.

The spearman correlation for dssim against the TID2008 dataset
is 0.81, against 0.70 for the old ssim implementation, and
it runs 15 times faster.

Review of attachment 305831 [details] [review]:

Id the purpose is only to support dssim this should
be conditionally built instead of ifdefing the dssim
bits around. Aditionally, I'd suggest changing the
element name to smth specific.

Now, if the idea is actually to support more than one
quality metric algo from the start (as the name seems to
imply), maybe adding a PSNR fallback & an enum property
to select between the available ones and modding compare_frame()
accordingly would be a good start.

Seems like a nice addition all the same!

Comment 4 Thibault Saunier 2016-11-17 16:38:40 UTC 
I made the plugin not build if dssim is not avalaible, I also added support for building with meson (with dssim as subproject) and made sure that if dssim can't be run, we fail loadly.

Thanks.
