In this paper, a new image database, TID2008, for evaluation of full-reference visual quality assessment metrics is described. It contains 1700 test images (25 reference images, 17 types of distortions for each reference image, 4 different
levels of each type of distortion). Mean Opinion Scores (MOS) for this database have been obtained as a result of more than 800 experiments. During
these tests, observers from three countries (Finland, Italy, and Ukraine) have carried out about 256000 individual human quality judgments. The obtained
MOS can be used for effective testing of different visual quality metrics as well as for the design of new metrics. Using the designed image database, we
have tested several known quality metrics. The designed test image database is freely available for downloading and utilization in scientific
