Project Summary: Quality of noise reduction in TV-systems
this report, several state-of-the-art noise reduction algorithms are ranked
using both subjective evaluation and twenty objective measures proposed
in literature. The goal of the study was to find the objective quality
measure that best relates to the subjective assessment for noise reduction.
A measurement set-up comprising a simulation of a TV-transmission channel
has been used to provide a realistic assessment of the performance in TV-applications
of algorithms reducing Gaussian white noise. Ranking results are given
of the subjective evaluation and all objective measures. The correlation
between the subjective evaluation results and the objective measures is
found to be very low. Results show that even a combination of objective
measures only approximates the subjective assessment of the quality of
noise reduction algorithms to a limited extent.
