Spatial anti-aliasing is a technique used in digital signal processing to reduce distortion when representing a high-resolution image at a lower resolution. It involves removing signal components that have a higher frequency than can be properly resolved by the recording device, which helps prevent artifacts such as black-and-white noise. This can be achieved through analog anti-aliasing filters in signal acquisition and audio, or optical anti-aliasing filters in digital photography.
