Abstract
According to one aspect of the present disclosure, a method for decoding a point cloud that is represented in a one-dimension (ID) array that includes a set of points is provided. The method may include identifying, by at least one processor, a maximum number of transform coefficients used to predict an attribute value of a point in the set of points. The method may include decoding, by the at least one processor, a bitstream to identify the maximum number of transform coefficients based on a logarithmic format minus a fixed integer.
Claims16
A method for decoding a point cloud, the point cloud being represented in a one-dimension (1D) array comprising a set of points, the method comprising:
- identifying, by at least one processor, a maximum number of transform coefficients used to predict an attribute value of a point in the set of points;
- and
- decoding, by the at least one processor, a bitstream to identify the maximum number of transform coefficients based on a logarithmic format minus a fixed integer.

A method for encoding a point cloud, the point cloud being represented in a one-dimension (1D) array comprising a set of points, the method comprising:
- identifying, by at least one processor, a maximum number of transform coefficients used to predict an attribute value of a point in the set of points;
- and
- encoding, by the at least one processor, a bitstream to indicate the maximum number of transform coefficients based on a logarithmic format minus a fixed integer.
16-20. (canceled)
A method for decoding a point cloud, the point cloud being represented in a one-dimension (1D) array comprising a set of points, the method comprising:
- identifying, by at least one processor, a maximum zero-run length associated with a plurality of attribute values associated with one or more points in the set of points;
- in response to a coded zero-run length being less than or equal to the maximum zero-run length, decoding, by the at least one processor, a bitstream in a single-loop process based on the zero-run length;
- and
- in response to the coded zero-run length being greater than the maximum zero-run length, decoding, by the at least one processor, the bitstream based on the maximum zero-run length and the coded zero-run length in a multi-loop process.
