摘要： Methods and apparatuses are provided for processing video data by using an object mask information (OMI) supplemental enhancement information (SEI) message. An exemplary encoding method includes: receiving a video sequence; and encoding one or more pictures of the video sequence to generate a bitstream, comprising: encoding an auxiliary picture indicating a mask of an object in a primary picture, the mask of the object being represented by a sample value of the auxiliary picture; and generating a supplemental enhancement information (SEI) message indicating an attribute of the mask of the object.

摘要： A method of encoding a video sequence into a bitstream. The method includes receiving a video sequence; performing a plurality of convolutions on an input image data of the video sequence in YUV format; wherein performing the plurality of convolutions includes performing a first stage convolution on the input image data, wherein the first stage convolution comprises a first convolution and a second convolution that are provided in parallel; performing a second stage convolution on a channel-wise concatenation result of an output of the first convolution and an output of the second convolution; performing a third stage convolution on an output of the second stage convolution; and obtaining an output image data based on an output of the third stage convolution; and encoding the output image data for generating the bitstream.
