Decoder-side inter prediction based on no reference visual quality

Abstract

A decoder decodes, from a bitstream for a current block, an indication of whether decoder-side inter prediction is enabled, and a reconstructed residual block. Based on the decoder-side inter prediction being enabled by the indication and for each respective motion information of a plurality of motion information, the decoder generates a reconstructed block based on: a prediction block generated using the respective motion information, and the reconstructed residual block. For each reconstructed block, the decoder determines a visual quality of the reconstructed block without using the current block as a reference. Based on the visual qualities of the reconstructed blocks, motion information for predicting the current block is determining from the plurality of motion information. The decoder reconstructs the current block based on the determined motion information.
