摘要:
There are provided methods and apparatus for weighted prediction in scalable video encoding and decoding. A scalable video encoder includes an encoder (100) for encoding a block in an enhancement layer of a picture by applying a weighting parameter to an enhancement layer reference picture. The weighting parameter used to encode the block in the enhancement layer is adaptively selected from between a weighting parameter applied to a lower layer reference picture to encode a block in the lower layer of the picture and a different weighting parameter applicable in the enhancement layer. The block in the enhancement layer corresponds to the block in the lower layer. The enhancement layer reference picture corresponds to the lower layer reference picture.
摘要(中):
提供了可扩展视频编码和解码中加权预测的方法和装置。 可分级视频编码器包括编码器(100),用于通过将加权参数应用于增强层参考图像来对图像的增强层中的块进行编码。 用于对增强层中的块进行编码的加权参数从应用于下层参考图片的加权参数之间自适应地选择,以对图像的下层中的块进行编码,以及可应用于增强层的不同加权参数。 增强层中的块对应于下层中的块。 增强层参考图片对应于下层参考图片。
