  • 14. Conclusion
    • MGA offersanextendedseriesofTrasformation
    • 15. New directionalfiltersbank
    • 16. The objectiveassessment results can well reflect the visual quality of images (good consistency with subjective perception values)
    • 17. The different transforms in MGA under the new framework perform better than the standard WNISM
    • 18. Some of them even perform better than the standard full-reference IQA model
    • 19. HWD performs best among all transforms in MGA under the framework
