Abstract
At least one disclosed method and apparatus relate to inter-view prediction with different resolution reference picture. A particular method includes accessing at least a portion of an encoded picture (614), the encoded picture being from a particular view of multiple views, and the portion being encoded at a particular resolution. The method further includes determining a particular view level based on the particular view (614), determining the particular resolution based on the particular view level (606), and decoding the portion based on the particular resolution (630).
Claims7
A method, comprising:
- accessing at least a portion of an encoded picture, the encoded picture being from a particular view of multiple views, and the portion being encoded at a resolution;
- determining the resolution of the particular view for at least the portion from information identifying an assigned view level and a resolution corresponding to the view level;
- and
- decoding at least the portion based on the determined resolution,
- wherein the determining comprises identifying the resolution for the particular view based on a position of the view level in a scalability hierarchy, the position being indicated by a particular view level and the scalability hierarchy provides scalability at least by allowing that pictures from a given position in the scalability hierarchy to be used as an inter-view reference for pictures from a less important position in the scalability hierarchy and not to be used as a reference for pictures from a more important position in the scalability hierarchy, and resolution for a picture from a given position in the scalability hierarchy being as good as resolution for a picture from a less important position in the scalability hierarchy, and wherein inter-view reference pictures are downsampled from a higher resolution picture before being used as a reference for pictures from a less important position in the scalability hierarchy.
An apparatus, comprising:
- a memory, and
- a processor, configured to:
- access at least a portion of an encoded picture, the encoded picture being from a particular view of multiple views, and the portion being encoded at a resolution;
- determine the resolution of the particular view for at least the portion from information identifying an assigned view level and a resolution corresponding to the view level;
- and
- decode at least the portion based on the determined resolution,
- wherein the determining comprises identifying the resolution for the particular view based on a position of the view level in a scalability hierarchy, the position being indicated by a particular view level and the scalability hierarchy provides scalability at least by allowing that pictures from a given position in the scalability hierarchy to be used as an inter-view reference for pictures from a less important position in the scalability hierarchy and not to be used as a reference for pictures from a more important position in the scalability hierarchy, and resolution for a picture from a given position in the scalability hierarchy being as good as resolution for a picture from a less important position in the scalability hierarchy, and wherein inter-view reference pictures are downsampled from a higher resolution picture before being used as a reference for pictures from a less important position in the scalability hierarchy.
