Hybrid Sparse and Dense Attentions of Similar Regions for Image Denoising
Daiqiang Chen
Abstract:Self-attention based on dot-product has achieved great success in the field of computer vision. Its effectiveness is owed to the large capacity of capturing long-range dependencies in feature maps. However, its quadratic computational complexity with respect to the image size hinders the further application of the self-attention modules. Therefore, a variety of strategies, which limit the regions of the computation of dot-product, have been proposed to reduce the computational amount. Through analyzing the adv… Show more
