摘要: Methods and apparatuses are provided for encoding and decoding video data based on a supplemental enhancement information (SEI) message. An exemplary method includes: generating a reconstrued frame sequence based on a compressed video; decoding a supplemental enhancement information (SEI) message with respect to the reconstrued frame sequence, according to the compressed video; and performing temporal upsampling to the reconstrued frame sequence based on the SEI message by using a neural network.

摘要: A method of decoding a bitstream to output one or more pictures for a video stream, includes: receiving a bitstream; and decoding, using coded information of the bitstream, one or more pictures. The decoding includes: determining, based on an identifying number, whether a face video generative compression scheme is used; in response to a determination that the face video generative compression scheme is used, decoding a supplemental enhancement information (SEI) message, the SEI message comprising facial information; and reconstructing a face picture based on the facial information and a base picture associated with the SEI message.

摘要: The present disclosure provides a video data processing method for cross-component sample adaptive offset (CCSAO). The method includes determining an index based on a vertical coordinate of a chroma sample within a picture; determining a luma sample based on the index; classifying the chroma sample based on a reconstructed value associated with the luma sample; determining an offset based on the classification; and adding the offset to a reconstructed value associated with the chroma sample.

摘要: During video encoding or decoding, cross-component prediction can be used to predict a chroma sample from collocated reconstructed luma samples. The prediction can be based on a gradient of the collocated reconstructed luma samples, a down-sampled value of the collocated reconstructed luma samples, or a combination thereof. An exemplary method includes: determining a first value associated with a chroma sample, by applying a first gradient pattern to reconstructed values of a first plurality of luma samples; determining a second value associated with the chroma sample, by applying a down-sampling filter to reconstructed values of a second plurality of luma samples; and predicting the chroma sample based on the first value and the second value.
