摘要：In this paper, we analyze the performance of TID2008 and LIVE databases for full-reference image quality assessment metrics. A comparative analysis is presented. The subjective testing method which is used to obtain the perceived quality scores affects the accuracy and reliability of the database. It is shown that there are the relationship between the reference images and the types of distortions with different distorted levels. Results are: 1) Both TID2008 and LIVE databases are not well for image subjective quality assessment. 2)The distributions of their parameters are not adequate andreasonable. 3)The subjective methodology should use both the reference image and the worst distortion image. © 2013 IEEE.
