Claim 25:
26. The non-transitory computer-readable storage medium of claim 22, wherein the instructions further cause the one or more processors to:
receive a second picture that includes a second plurality of subpictures;
decode a second quality metrics SEI message associated with the second plurality of subpictures of the second picture, the second quality metrics SEI message including:
a second syntax element indicative of a second number of subpictures within the second plurality of subpictures,
a second quality metric type syntax element, associated with a second at least one subpicture of the second plurality of subpictures, set to a third value among the plurality of values that respectively indicate the plurality of types of quality metrics, where the third value is set to 1, and
a second quality metric syntax element specifying a fourth value;

determine that the second quality metric type syntax element is set to 1;
based on the determination that the second quality metric type syntax element is set to 1, determine to interpret the fourth value specified by the second quality metric syntax element as a value indicative of a SSIM associated with the second at least one subpicture; and
derive, based on the fourth value specified by the second quality metric syntax element, a derived SSIM associated with the second at least one subpicture.
