Abstract
A method of block-wise neural image compression with post filtering is performed by at least one processor of an encoder and includes encoding a block of an input image, using a first neural network, wherein the encoded block is decoded by a decoder using a second neural network to generate a reconstructed block, and performing intra-prediction on the reconstructed block, using a third neural network, to generate a predicted block. The method further includes determining a difference between the block of the input image and the generated predicted block, to generate a prediction residual, encoding the generated prediction residual, using a fourth neural network, wherein the encoded prediction residual is decoded by the decoder using a fifth neural network, and adding the decoded prediction residual to the generated predicted block, to generate a recovered predicted block.
