What is anti-aliasing example?

Anti-aliasing is the smoothing of jagged edges in digital images by averaging the colors of the pixels at a boundary. The letter on the left is aliased. The letter on the right has had anti-aliasing applied to make the edges appear smoother.

What is the filter used for anti-aliasing?

An anti-aliasing filter (AAF) is a filter used before a signal sampler to restrict the bandwidth of a signal to satisfy the Nyquist–Shannon sampling theorem over the band of interest.

What is the best anti-aliasing filter?

SSAA still produces the best anti-aliasing results, but it's also the most demanding, as it's essentially rendering the image at a higher resolution.
