Non-Sampled Anti-Aliasing
In this paper we present a parallel method for high-quality edge anti-aliasing in rasterization. In contrast to traditional graphics hardware methods, which rely on massive oversampling to combat aliasing issues, we evaluate a closed-form solution of the associated prefilter convolution. This enables the use of a wide range of filter functions with arbitrary kernel sizes, as well as general sha...
متن کاملFilter basics: anti-aliasing - AN928
In a sampled data system, frequency components greater than half the sampling rate "alias" (shift) into the frequency band of interest. Most of the time, aliasing in an undesirable side effect, so the "undersampled" higher frequencies are simply filtered out before the A/D stage. But sometimes, the undersampling is deliberate and the aliasing causes the A/D system to function as a mixer. This a...

متن کاملTime-domain aliasing cancellation role in error concealment - Electronics Letters
Introduction: Audio technology has come a long way from magnetic tape recording in the early twentieth century to the current digital music technology. The increase in Internet audio streaming and digital audio broadcasting poses a new challenge, as they are often subject to bandwidth limitation that is incompatible with the high data rate of digital music. However, with the current perceptual ...
