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
• Spatial anti-aliasing, the technique of minimizing aliasing when representing a high-resolution image at a lower resolution
  • Supersample anti-aliasing, a method of smoothing images rendered in computer-generated imagery
    • Multisample anti-aliasing, a type of anti-aliasing, a technique used in computer graphics to improve image quality
• Temporal anti-aliasing, techniques to reduce or remove the effects of temporal aliasing
