Abstract
A device may be configured to perform spatial extrapolation based on information included in a neural-network post-filter characteristics message. In one example, a neural-network post-filter characteristics message includes a syntax element indicating a purpose of the neural-network post-filter characteristics message is spatial extrapolation. In one example, a neural-network post-filter characteristics message includes a syntax element specifying a text string prompt used for generating contents of a spatial extrapolation image area.
Claims4
A method of decoding video data, the method comprising:
- receiving a neural-network post-filter characteristics message;
- parsing a first syntax element in the neural-network post-filter characteristics message, wherein the first syntax element indicates a purpose of a neural-network post-filter characteristics message is spatial extrapolation;
- and
- parsing a second syntax element in the neural-network post-filter characteristics message, wherein the second syntax element is a null-terminated string encoded as universal coded character set (UCS) transmission format-8 (UTF-8) characters and specifies a text string prompt used for generating contents of a spatial extrapolation image area.
A device comprising one or more processors configured to:
- receive a neural-network post-filter characteristics message;
- parse a first syntax element in the neural-network post-filter characteristics message, wherein the first syntax element indicates a purpose of a neural-network post-filter is spatial extrapolation;
- and
- parse a second syntax element in the neural-network post-filter characteristics message, wherein the second syntax element is a null-terminated string encoded as universal coded character set (UCS) transmission format-8 (UTF-8) characters and specifies a text string prompt used for generating contents of a spatial extrapolation image area.
