Abstract: Encoding a three-dimensional point cloud. A set of points are obtained within the three-dimensional point cloud, a point within the set of points having a co-ordinate in three-dimensions. The points are converted into a two-dimensional representation. For a point within the set of points, information describing the co-ordinate is represented as a location within the two-dimensional representation and a value at the location. The two-dimensional representation is encoded using a tier-based hierarchical coding format to output encoded data. The tier-based hierarchical coding format encodes the two-dimensional representation as layers, the layers representing echelons of data used to progressively reconstruct the signal at different levels of quality.

Abstract: Examples of a low complexity enhancement video coding are described. Encoding and decoding methods are described, as well as corresponding encoders and decoders. The enhancement coding may operate on top of a base layer, which may provide base encoding and decoding. Spatial scaling may be applied across different layers. Only the base layer encodes full video, which may be at a lower resolution. The enhancement coding instead operates on computed sets of residuals. The sets of residuals are computed for a plurality of layers, which may represent different levels of scaling in one or more dimensions. A number of encoding and decoding components or tools are described, which may involve the application of transformations, quantization, entropy encoding and temporal buffering. At an example decoder, an encoded base stream and one or more encoded enhancement streams may be independently decoded and combined to reconstruct an original video.
