    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (408 KB)

    The RAI Research Centre is developing studies to find a correlation between objective measures of video impairments and human perception. Such measures should replace subjective assessment, that is, they should allow the performance evaluation of a given system without consulting any of the users. This is a difficult problem to solve because compression systems introduce new kinds of impairments o... View full abstract»
