question about niqe

[suke27]

niqe score higher means better. it seems not stable, sometimes it can get high score for low quality image, sometimes low score

@suke27 Could you please provide an example?

I have tested NIQE only with blur (gaussian blurs from small to large) and compression (jpg quality from high to low). It seems to behave as expected in those cases, on a small sample set. However people have also reported that the NIQE scores don't match Matlab's version, so there may be a bug here as well.

I have a question here that NIQE score is the higher the better or on the opposite. I am confused here.
