Morphological Antialiasing (MLAA)

Morphological Antialiasing (MLAA)

Intel Corporation


Features / Description

MLAA is an image-based, post-process filtering technique which identifies discontinuity patterns and blends colors in the neighborhood of these patterns to perform effective anti-aliasing. It is the precursor of a new generation of real-time antialiasing techniques that rival MSAA. This sample is based on the original, CPU-based MLAA implementation provided by Reshetov in 2009, with improvements to greatly increase performance. The improvements are:

  • Integration of a new, efficient, easy-to-use tasking system implemented on top of Intel® Threading Building Blocks (Intel® TBB).
  • Integration of a new, efficient, easy to use pipelining system for CPU onloading of graphics tasks.
  • Improvement of data access patterns through a new transposing pass.
  • Increased use of Intel® SSE instructions to optimize discontinuities detection and color blending.

 

This sample also contains MLAA implementation for Intel HD graphics, called separable antialiasing (SAA). It runs 2.5x faster than previous state-of-the-art GPU implementations of MLAA, achieving about 1000 fps for a 1 Mpixel image resolution on Intel’s latest graphics hardware.

 
Viewing the found edges can be helpful when debugging MLAA. The MLAA sample contains a zoom box to compare different anti-aliasing techniques.
