v.Cortex Perceptual

Analyzer

v.Cortex discovers

video scenes that do

not meet your

customers’ quality

expectations

v.Cortex is a No Reference Model

Encoder

The human visual system (HVS) is aware of

MPEG impairments without seeing

original, or source video. v.Cortex is a no-

reference model, like the HVS, and does

not require source material to estimate

quality.
