Abstract
Official abstract text for this publication.
A filter unit determines a mapping of range combinations to filters. Each range combination includes a range for a first metric and a range for a second metric. The filter unit determines a unique range combination identification (ID) for each range combination, with each unique range combination ID corresponding to a sequential value. The filter unit assigns a unique group ID to each group of range combinations. A group of range combinations includes range combinations mapped to the same filter, and the unique group IDs correspond to a set of sequential values. The filter unit signals or reconstructs coefficients for the filters in an order based on the sequential values of the group IDs.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of coding video data, the method comprising: determining a mapping of range combinations to filters, wherein a range combination comprises a range for a first metric and a range for a second metric, wherein each range combination has a unique range combination identification (ID), wherein each unique range combination ID corresponds to a sequential value for a range combination, wherein the first metric is determined based on pixel valu…
