PEVQ™ Analyzer

In

the

course

of

International

Standardization of video quality metrics, in
2007 and 2008 the Video Quality Experts
Group (www.vqeg.org) conducted a huge
test series of 41 validation tests run across
twelve different labs in Europe, USA and
Asia. OPTICOM's PEVQ showed superior
performance and is going to be proposed
for standardization. Most importantly,
PEVQ could also significantly outperform
PSNR, a commonly used industry metrics
for objective video quality estimation.

The accuracy of PEVQ has been trained on
a huge number of human visual test data-
bases. The photo shows OPTICOM's sub-
jective test setup which is in line with ITU-
T Rec. P.910 and further adaptations devel-
oped by VQEG for the multimedia test
series.
