US Patent 12015785 No reference image quality assessment based decoder side inter prediction

A decoder may determine first motion information, from of a plurality of motion information, for a block. The decoder may generate, for each respective motion information of the plurality of motion information, a reconstructed block. The decoder may generate the reconstructed block, for each respective motion information of the plurality of motion information, based on: a prediction block generated for the respective motion information; and a reconstructed residual block based on the first motion information. The decoder may determine second motion information, from the plurality of motion information, for the block based on a visual quality of each of the reconstructed blocks. The decoder may signal, based on the second motion information, the first motion information in a bit stream.
