Anti-aliasing may refer to any of a number of techniques to combat the problems of aliasing in a sampled signal such as a digital image or digital audio recording.
Specific topics in anti-aliasing include:
Anti-aliasing filter, a filter used before a signal sampler, to restrict the bandwidth of a signal
Spatial anti-aliasing, the technique of minimizing aliasing when representing a high-resolution image at a lower resolution
Supersample anti-aliasing (SSAA), a type of spatial anti-aliasing method
Multisample anti-aliasing (MSAA), a type of spatial anti-aliasing method
Fast approximate anti-aliasing (FXAA), an anti-aliasing algorithm created by Timothy Lottes under NVIDIA
Coverage Sampling anti-aliasing (CSAA), a technology first used in GeForce 8 Series
Temporal anti-aliasing, techniques to reduce or remove the effects of temporal aliasing
