Note(s): “Layer 1” represents modification on the first multi-res dense, “Layer 1–2” denotes modification on the first and second multi-res dense and “Layer 1–4” denotes modification on the overall multi-res dense. “ $ω$ ” is the weight of SSIM loss in subjective loss. The best results are bold for viewing
