aliasing

It is calculated as half of the value of the sampling rate.Passing this level causes aliasing distortion, or foldover.

它的计算方法是将采样率除以二，超数值将会导致折叠失真，或称折叠。

Our approach is based on a gradient domain technique that preserves important local perceptual cues while avoiding traditional problems such as aliasing, ghosting and haloing.

我们的方法是一种基于梯度方法的技术，保存了重要的局部视觉暗示并避免了传统的混淆，鬼影和光晕的问题。
