Multi-scale discriminators for Dy and Dx. Left: We construct an image pyramid from the generated label (or image), and feed patches from this pyramid to multiple patch-based discriminators. Right: Single-scale discriminators with small receptive fields (top) tend to produce accurate local structure, but inaccurate repetitive global structure. Similarly, single-scale discriminators with large receptive fields produce accurate global structure, but fail to generate accurate local textures.
