Patent attributes
Techniques and systems are provided for processing 360-degree video data. For example, a picture of the 360-degree video data can be obtained. The picture can include samples projected from a three-dimensional format to a two-dimensional format. A weight value can be determined for at least one sample of the picture. The weight value can be determined based at least on a position of the at least one sample in the picture. At least one adaptive parameter can be determined for the at least one sample using the determined weight value. The at least one adaptive parameter can include one or more of an adaptive weighted distortion, an adaptive weighted quantization parameter value, or an adaptive weighted lambda value. A cost associated with coding the at least one sample using one or more coding modes can be determined using the at least one adaptive parameter of the at least one sample.
