Anti-aliasing
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 such as in audio applications
- 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).
- Multisample anti-aliasing, a type of spatial anti-aliasing method
- Supersampling, a type of spatial anti-aliasing method
- Temporal anti-aliasing, techniques to reduce or remove the effects of temporal aliasing in moving images
