Fighting the Wagon-Wheel Effect–A New Anti-Aliasing Method for Video Signal Generation

摘要：

In this paper a new method of avoiding aliasing effects in synthetically generated video is presented. In other words, aim is to remove aliasing effects that disturb visual perception of the synthetically generated image sequence by the human eye. In general, aliasing occurs if the widely known sampling theorem is not met. In the field of video applications, more often than not the limiting factor leading to these disturbing effects is the temporal sampling rate (a.k.a. “frame rate). The standard approach known from 1-D signal processing applications, i.e. increasing the sampling rate, is effective but very hardwareexpensive as it introduces additional frames that have to be processed by the underlying system. In contrast, the proposed method uses a cheap 1-D filter in space-direction to achieve the same aliasing-free result.
