Super resolution GAN Model

[muschellij2]

Default for SuperResolutionGanModel is bad for 64x64x3, but needs to be 112x112x3. Technically the product needs to be 25088/2 = 12544

library( keras )
library( ANTsRNet )

ganModel <- SuperResolutionGanModel$new(lowResolutionImageSize = c( 112, 112, 3 ))
