Image Super-Resolution Reconstruction Algorithm Based on Adaptive Two-Branch Block
Recently,attention mechanisms have been widely applied for image super-resolution reconstruction,substantially improving the reconstruction network's performance.To maximize the effectiveness of the attention mechanisms,this paper proposes an image super-resolution reconstruction algorithm based on an adaptive two-branch block.This adaptive two-branch block designed using the proposed algorithm includes attention and nonattention branches.An adaptive weight layer would dynamically balance the weights of these two branches while eliminating redundant attributes,thereby ensuring an adaptive balance between them.Subsequently,a channel shuffle coordinate attention block was designed to achieve a cross-group feature interaction to focus on the correlation between features across different network layers.Furthermore,a double-layer residual aggregation block was designed to enhance the feature extraction performance of the network and quality of the reconstructed image.Additionally,a double-layer nested residual structure was constructed for extracting deep features within the residual block.Extensive experiments on standard datasets show that the proposed method has a better reconstruction effect.
