Morphological antialiasing (MLAA) is a technique for minimizing the distortion artifacts known as
aliasing
In signal processing and related disciplines, aliasing is a phenomenon that a reconstructed signal from samples of the original signal contains low frequency components that are not present in the original one. This is caused when, in the ori ...
when representing a high-resolution image at a lower resolution.

multisample anti-aliasing
Multisample anti-aliasing (MSAA) is a type of spatial anti-aliasing, a technique used in computer graphics to remove jaggies.
It is an optimization of supersampling, where only the necessary parts are sampled more. Jaggies are only noticed in ...
(MSAA), which does not work for
deferred rendering, MLAA is a
post-process filtering which detects borders in the resulting image and then finds specific patterns in these. Anti-aliasing is achieved by blending pixels in these borders, according to the pattern they belong to and their position within the pattern.
Enhanced subpixel morphological antialiasing, or SMAA, is an
image-based GPU-based implementation of MLAA developed by
