TAMPERE IMAGE DATABASE 2008 TID2008

This post is a useful link to Tampere Image Database (TID) and visual quality metric test suite, that I would like to have close at hand.
TID is intended for evaluation of full-reference image visual quality assessment metrics. TID allows estimating how a given metric corresponds to mean human perception. For example, in accordance with TID2008, Spearman correlation between the metric PSNR (Peak Signal to Noise Ratio) and mean human perception (MOS, Mean Opinion Score) is 0.525.
