The Nyquist theorem requires a sampling rate of at least twice the highest frequency of the signal; an improperly set sampling rate causes high-frequency components to fold over and create aliasing noise.

UnverifiedStaged upsampling, which replaces a single large-scale magnification with multiple smaller ones, can reduce ringing, blurring, or checkerboard artifacts, and allows sharpening and denoising nodes to be inserted between the two steps for refined image quality.72% similarUnverifiedMax pooling is essentially a downsampling operation without anti-aliasing filtering, which violates the Nyquist sampling theorem and causes high-frequency information to fold into the low-frequency region, producing aliasing.71% similar
