Abstract
A method and apparatus for coding video data includes filtering video data using a loop filter, such as an adaptive loop filter (ALF), that is determined using a classifier from a plurality of classifiers. A video coder may reconstruct a block of video data to generate a reconstructed block, determine a filter class for the reconstructed block using a classifier from a plurality of classifiers, wherein the plurality of classifiers includes one or more of a first classifier based on a geometry partition and a second classifier based on a histogram of gradients, determine a filter based on the filter class, and apply the filter to the reconstructed block.
