AHG9: Colour component description for post-filter purpose SEI message
Authors: Takeshi Chujoh Sharp Yukinobu Yasugi Sharp Keiichiro Takada Sharp Tomohiro Ikai Sharp
Abstract
At the previous meeting, the SEI message for sending network parameters of neural network and the SEI message for purposes of post-filter was proposed by JVET-X0112. Multiple companies have presented the same concept at the past several meetings. This contribution suggests maintaining the two-layered SEI structure and proposes that the post-filter purpose SEI message specifies the input or output sample interface for the post-filtering process. For example, it should describe the updating colour components and the output chroma format.

JVET-Y0073 AHG9: Colour component description for post-filter purpose SEI message [T. Chujoh, Y. Yasugi, K. Takada, T. Ikai (Sharp)]

At the previous meeting, the SEI message for sending network parameters of neural network and the SEI message for purposes of post-filter was proposed by JVET-X0112. Multiple companies have presented the same concept at the past several meetings. This contribution suggests maintaining the two-layered SEI structure and proposes that the post-filter purpose SEI message specifies the input or output sample interface for the post-filtering process. For example, it should describe the updating colour components and the output chroma format.

High level interface (JVET-Y0073) specifies the input and output chroma sampling formats of the post filter
