Title
(EN) AN APPARATUS, A METHOD AND A COMPUTER PROGRAM FOR VIDEO CODING AND DECODING
(ZH) 用于视频编码和解码的装置、方法及计算机程序
Abstract
(EN)
There is provided a method comprising encoding an uncompressed constituent frame into a first encoded picture, said encoding also resulting into a reconstructed first picture and said constituent frame having an effective picture area within the first reconstructed picture, performing either of the following as a part of said encoding: inserting at least one sample value outside the effective picture area to form a boundary extension for the constituent frame in the reconstructed first picture; or saturating or wrapping oversample locations outside the effective picture area to be within the effective picture area. There is also provided a method comprising receiving an encoded picture, decoding the encoded picture to form a reconstructed constituent frame of the picture having an effective picture area; and performing either of the following: filling an area outside the effective picture area to produce a padded reference picture, wherein the filled area forms a boundary extension; ordetermining that when referring to sample locations outside the effective picture area in decoding, said sample locations are saturated or wrapped over to be within the effective picture area.

提供一种方法,其包括:将未压缩构成帧编码成第一编码图像,所述编码还导致第一重建图像,并且所述构成帧具有所述第一重建图像内的有效图像区域;执行以下操作之一作为所述编码的一部分:在所述有效图像区域以外插入至少一个样本值,以形成所述第一重建图像中的所述构成帧的边界扩展;或者将所述有效图像区域以外的样本位置充满或叠起在所述有效图像区域内。还提供一种方法,其包括:接收编码图像;解码所述编码图像以形成具有有效图像区域的所述图像的重建构成帧;以及执行以下操作之一:填充所述有效图像区域以外的区域以产生填补参考图像,其中,所填充的区域形成边界扩展;或者确定当在解码中参考所述有效图像区域以外的样本位置时,所述样本位置被充满或叠起在所述有效图像区域内。
