Anti-aliasing filter, a filter used before a signal sampler, to restrict the bandwidth of a signal such as in audio applications
Manual anti aliasing, artistic technique done in pixel art graphics to smooth transitions between shapes, to soften lines or to blur edges.
Spatial anti-aliasing, the technique of minimizing aliasing when representing a high-resolution image at a lower resolution
Fast approximate anti-aliasing, an anti-aliasing algorithm created by Timothy Lottes under Nvidia. May also be referred to as Fast Sample Anti-aliasing (FSAA).
