“…Deep CNN have shown impressive improvement in image processing tasks especially in the super-resolution (SR) reconstruction field. High-resolution images provide enhanced reconstructed details of both scenes and objects, which are essential for applications in many other domains like image segmentation (Li et al, 2019;Chen et al, 2017;Wang et al, 2020a), small object detection (Bai et al, 2018), medical imaging (Greenspan, 2009), remote sensing (Lillesand et al, 2015), fingerprint identification (Alsmirat et al, 2019), and image retrieval (Wang et al, 2020b;Chen et al, 2020;Aghav-Palwe and Mishra, 2020).…”
