ITU-T P.800 (mean opnion score)ITU-T P.862 (PESQ)

ITU-T P.862.1 (PESQ)

ITU-T G.107 (R Factor)

The relations between this R value on a scale of 0 to 100 and

the MOS of previous methods have been drawn as a clipped

third degree polynomial function, which give a bidirectionaltransformation between the two grade systems
