A new anti-aliasing algorithm for computer graphics images

This paper presents an area-filtering algorithm for anti-aliasing technique of computer graphics images. It can be applied to low-resolution image, which the aliasing effect is more visible. Unlike supersampling technique, which costs too much to do well, this technique is simple and suitable for VLSI implementation. Without changing the current PC-based graphics-hardware architecture, this technique costs little overhead and improves the image quality of aliasing images 5~10 dB on the average.
