Figure 6

Performance of the blurring measure, the ringing measure, and the proposed sharpness metric on LIVE database, TID2008 database, and CSIQ database. (a) The dot plot figure of the blurring measure versus the corresponding MOS on LIVE database, TID2008 database, and CSIQ database (from left to right). (b) The result of the ringing measure on these three databases. (c) The result of the proposed metric.
