TAMPERE IMAGE DATABASE 2013 TID2013, version 1.0


TID2013 is intended for evaluation of full-reference image visual quality assessment metrics. TID2013 allows estimating how a given metric corresponds to mean human perception. For example, in accordance with TID2013, Spearman correlation between the metric PSNR (Peak Signal to Noise Ratio) and mean human perception (MOS, Mean Opinion Score) is 0.69.

How to test your metric? Step 1. Download the TID2013. Step 2. Calculate values of your metric for each distorted image of TID2013. Step 3. Use included software ("spearman.exe" or "kendall.exe") for calculate a correlation between your metric and MOS.

In case of publishing results obtained by means of TID2013 please refer to one of following paper:

The TID2013 contains 25 reference images and 3000 distorted images (25 reference images x 24 types of distortions x 5 levels of distortions). Reference images are obtained by cropping from Kodak Lossless True Color Image Suite. All images are saved in database in Bitmap format without any compression. File names are organized in such a manner that they indicate a number of the reference image, then a number of distortion's type, and, finally, a number of distortion's level: "iXX_YY_Z.bmp".

The file "mos.txt" contains the Mean Opinion Score for each distorted image. The MOS was obtained from the results of 971 experiments carried out by observers from five countries: Finland, France, Italy, Ukraine and USA (116 experiments have been carried out in Finland, 72 in France, 80 in Italy, 602 in Ukraine, and 101 in USA). Totally, the 971 observers have performed 524340 comparisons of visual quality of distorted images or 1048680 evaluations of relative visual quality in image pairs. Higer value of MOS (0 - minimal, 9 - maximal, MSE of each score is 0.018) corresponds to higer visual quality of the image.

We plan to regularly update the versions of this database. New versions will include new types of distortion and take into account results of additional experiments.

We will highly appreciate authors of other metrics if they will inform us (please, mail to nikolay@ponomarenko.info) how to get executable files (e.g., Matlab codes) of their metrics. We guarantee that we will not pass them to other users and will include future results obtained for such metrics in analysis for our database.
