'aliasing'是英语词汇,中文翻译为“赛建”、“赛频”、“混叠”。
该词语是计算机图像处理中的术语,指由于信号采样率过低,导致高频信息被误认为低频信息的情况,表现为图像出现锯齿状的现象。这种现象通常会影响图像的质量和精度,需要采用一些特殊的算法来解决。
以下是9个含有'aliasing'的例句:
1. In digital photography, aliasing can occur when the frequency of the signal exceeds the Nyquist frequency.
(在数码摄影中,当信号频率超过奈奎斯特频率时,就会出现赛频现象。)
2. To avoid aliasing, it is necessary to sample the signal at a rate higher than twice the highest frequency of interest.
(为了避免赛频现象,必须以高于兴趣最高频率两倍的速率对信号进行采样。)
3. When using anti-aliasing filters, it is important to choose a filter with the appropriate cut-off frequency.
(在使用抗赛频滤波器时,选择具有适当截止频率的滤波器非常重要。)
4. Aliasing artifacts can be reduced by using a higher-resolution display.
(通过使用更高分辨率的显示器,可以减少赛频伪像。)
5. In video games, anti-aliasing techniques can be used to smooth out jagged edges.
(在视频游戏中,可以使用抗赛频技术来平滑锯齿状的边缘。)
6. Aliasing is a common problem in digital signal processing.
(赛频是数字信号处理中常见的问题。)
7. Oversampling can help to reduce the effects of aliasing.
(过采样可以帮助减少赛频效应。)
8. In audio processing, aliasing can result in unwanted noise and distortion.
(在音频处理中,赛频可能导致不必要的噪音和失真。)
9. Aliasing can be prevented by using a low-pass filter to remove high-frequency components from the signal.
(通过使用低通滤波器从信号中去除高频成分,可以避免赛频现象。)
