Picture coding method and picture decoding method
TLDR
A picture encoding method is a method of predictively encoding an input picture with reference to pictures stored in a picture buffer, decoding the encoded input picture, judging whether or not the decoded picture is a picture for reference as discussed by the authors.Abstract:
A picture encoding method of the present invention is a picture encoding method of predictively encoding an input picture with reference to pictures stored in a picture buffer, decoding the encoded input picture, judging whether or not the decoded picture is a picture for reference and whether or not the decoded picture is a picture for output which needs to be stored until its display time, and storing, in the picture buffer, the picture for reference and the picture for output based on the determination result.read more
