In evaluation of results of TMOs objective image quality metrics are often used for practical reasons. Since these metrics only approximate perceptual evaluation, they are sometimes too sensitive to perceptually unimportant details. In this paper such sensitivities of three recent tone mapped image quality metrics are compared: TMQI, TMQI-II, and FSITM. The comparison is performed by using specifically designed tone mapped images to check the measures' susceptibility to perceptually unnoticeable changes in brightness of the resulting image. It is shown that while values of TMQI and FSITM are only slightly affected by such changes, the recent TMQI-II can obtain significantly different values, which brings into question its ability perform a fair TMO comparison. The results are presented and discussed.}, doi = {10.20532/ccvw.2016.0005}, url = {https://doi.org/10.20532/ccvw.2016.0005} }
