Abstract
A video coder is configured to perform a neural network (NN)-based filter process on reconstructed blocks of vide data. In one example, a video coder may receive a picture of video data, and reconstruct a block of the picture of video data to generate a reconstructed block. The video coder may perform the NN-based filter process on the reconstructed block to generate a filtered block, wherein the NN-based filter process includes performing a plurality separable convolutions to approximate a multi-dimensional convolution.
