Abstract

A method for video processing includes receiving an input image via an initial feature extraction portion, where the initial feature portion includes a result of RPR up-sampling, a low resolution (LR) reconstructed frame, and an LR predicted frame; processing the input image by a first convolution layer; and processing the input image by a multi-level semantic information mapping portion to generate a combined image, where the multi-level semantic information mapping portion includes one or more residual spatial and channel attention blocks (RSCBs). Each of the RSCBs includes two or more residual spatial blocks (RSBs) and a channel attention (CA) block. Each of the RSBs includes a spatial attention (SA) block.
