when i do 360tools_metric, and the results show "QM_ID=1 8.82 8.64 8.56". could you tell me what the three numbers behind QM_ID mean?

Same issue. Could you please let us know which of the three values to consider as the quality score.

Hello. From my understanding, each score is for a separate color channel (in YUV format). One paper uses a private WS-PSNR calculation, and that's how they describe it - I am assuming the same applies here.

If anyone else has feedback, it would be great to confirm this is true.

See table 6.
