GAN-Based Image Super-Resolution with a Novel Quality Loss

Figure 2

The upper is the architecture of the generator , which employs the basic architecture of SRResNet [24]. Here, the original residual block is replaced with RRDB block. The lower left depicts the internal structure of each RRDB block and the lower right presents the internal structure of each dense block. Notably, the dense block of RRDB is comprised of convolutions and ReLUs without BN layers.
