A Fast Anti-aliasing Algorithm Based on Subpixel Technology

In currently widely used raster display system, the phenomenon of graphic display aliasing is common, such as non- horizontal and non-vertical line or polygon drawing. According to the linear aliasing producing principle, many scholars have proposed different anti-aliasing algorithms. During the algorithms there are many issues such as algorithm precision, memory spending, algorithm complexity and so on. We put forward an image sub pixel filling algorithm based on integral operations, not only the computing speed is fast, but also the anti-aliasing effect is quit good.
