Implementary Details

Network architecture: MAB number (n_resblocks): 5/24/36, channel width (n_feats): 48/60/180 for tiny/light/base MAN.

Overview of the proposed MAN constituted of three components: the shallow feature extraction module (SF), the deep feature extraction module (DF) based on multiple multi-scale attention blocks (MAB), and the high-quality image reconstruction module.

 

Component details: three multi-scale decomposition modes are utilized in MLKA. The 7×7 depth-wise convolution is used in the GSAU.

Details of Multi-scale Large Kernel Attention (MLKA), Gated Spatial Attention Unit (GSAU), and Large Kernel Attention Tail (LKAT).

 

Results and Models

Pretrained models avialable at Google Drive and Baidu Pan (pwd: mans for all links).

Results of our MAN-tiny/light/base models. Set5 validation set is used below to show the general performance. The visual results of five testsets are provided in the last column.
