Anti-aliasing is generally an expensive process because either super-sampling or sophisticated rendering is required. This paper presents a new type of antialiasing filter, pixel tracing filler, for animation sequences, which does not require an additional sample or additional calculation in the rendering phase. The filter calculates the correlation among the images using animation information, and sub-pixel information is extracted from the sequence based on the correlation. Theoretical studies prove that the filter becomes an ideal anti-aliasing filter in the limit that the filter size is infinite. The algorithm is simple image processing implemented as post-filtering. The computational cost is independent of the complexity of the scene. Experiments demonstrate the efficiency of the scene. Experiments demonstrate the efficiency of the filter. Almost complete anti-aliasing was achieved at the rate of approximately 30 s per frame for very complex scenes at the resolution of 256 x 256 pixels. The pixel-tracing filter provides effective anti-aliasing for animation sequences at a very modest computational cost.
