Abstract
There is provided a computer-implemented method for learned video compression, which includes processing a current frame (x) and previously decoded frame ({circumflex over (x)}) of a video data using a motion estimation model to estimate a motion vector (v) for every pixel, compressing the motion vector (v) and reconstructing the motion vector (v) to a reconstructed motion vector ({circumflex over (v)}), applying an enhanced context mining (ECM) model to obtain enhanced context ({umlaut over (C)}) from the reconstructed motion vector ({circumflex over (v)}) and previously decoded frame feature (x̆), compressing the current frame (x) with the assistance of the enhanced context ({umlaut over (C)}) to obtain a reconstructed frame ({circumflex over (x)}'), and providing the reconstructed frame ({circumflex over (x)}′) to a post-enhancement backend network to obtain a high-resolution frame ({circumflex over (x)}).
