The verification tests basically were carried out applying the test methods described in Recommendations ITU-R BT.500 [BT500] and ITU-T P.910 [P910]. In some cases, slight modifications to the standard test procedures were applied, to improve the reliability of test results; in other cases, important modifications were introduced, to properly evaluate new MPEG-4 functionalities. In the latter case, these modifications were proposed to the ITU groups in charge of developing subjective test methodology; they were included in the above-mentioned recommendations.
The test methods used for the MPEG-4 video verification tests are listed below:
Single stimulus (SS)
Double stimulus impairment scale (DSIS)
Double stimulus continuous quality ...
