AHG9: Enable the use of segmentation planes with the DI SEI message
Authors: S. Xie ZTE Ping Wu ZTE Yiling Gao ZTE Weihong Niu ZTE Yaxian Bai ZTE
Abstract
This contribution proposes to enable the use of a segmentation plane auxiliary picture with the Danmu Information (DI) SEI message, to support the function of face area avoidance. In detail, it is proposed to indicate a specific layer among the segmentation auxiliary layers associated with the same primary layer with an index di_segment_layer_idx. Additionally, the presence of di_segment_layer_idx is gated by di_segment_channel_adaptation_flag equal to 1.
Meeting Notes
JVET-AP0153 AHG9: Enable the use of segmentation planes with the DI SEI message [S. Xie, P. Wu, Y. Gao, W. Niu, Y. Bai (ZTE)]

This contribution proposes to enable the use of a segmentation plane auxiliary picture with the Danmu Information (DI) SEI message, to support the function of face area avoidance. In detail, it is proposed to indicate a specific layer among the segmentation auxiliary layers associated with the same primary layer with an index di_segment_layer_idx. Additionally, the presence of di_segment_layer_idx is gated by di_segment_channel_adaptation_flag equal to 1.

Proposal is related to previous proposal JVET-AN0259, but uses an associated picture segmentation information SEI and auxiliary layer.

It was questioned if it is the most appropriate solution to signal this information rather than leaving freedom to the receiver.

Colour mapping information (CMI) SEI message (4)
