MULTI-METRIC FILTERING

摘要

A filter unit of a video encoder or video decoder can determine a first metric for a group of pixels within a block of pixels, determine a second metric for the group of pixels, determine a filter based on the first metric and the second metric, and generate a filtered image by applying the filter to the group of pixels. The first metric and second metric can be an activity metric and a direction metric, respectively, or can be other metrics such as an edge metric, horizontal activity metric, vertical activity metric, or diagonal activity metric.
