Abstract
Example methods and devices are disclosed relating to the use of adaptive loop filter classifiers. An example method includes determining a sum of absolute values of one or more reconstructed residual sample values within a window associated with a block of the video data. The example method includes determining a class index based at least in part on the sum of absolute values. The example method includes determining an adaptive loop filter based on the class index. The example method includes applying the adaptive loop filter to a current to-be-filtered sample of the block. The example method includes decoding the block based on the application of the adaptive loop filter.
