Aliasing and Image Enhancement Test

In this quiz we will ask about spatial aliasing and anti-aliasing.

Frequency and spatial domain image enhancement operates directly on the pixels of an image.

Aliasing would happen if we have very high frequencies in a scene.

Which operation cannot be used as anti-aliasing?

Spatial domain operations are usually more costly than frequency domain operations.

If an image is enhanced in frequency domain, the inverse transform is not required
