We commonly observe aliasing on television. This occurs when there is an insufficient magnification produced by the lens of a TV camera focused on periodic structures such as the pattern of pinstripes in an announcer's shirt, bricks in the wall of a house, or seats in an empty stadium.Dougl...
Aliasingeffects are specially heavy in the specific application environment of space remote sensing imaging. CCD空间 推扫遥感成像中,特殊的应用条件,使得欠采样噪声效应尤为强烈. 互联网 Super - dynamic, interactive , vector - based animation, and sound. Presents graphics with zoom, anti -aliasing, and...
Related to aliasing:Anti aliasing a·li·as·ing (ā′lē-ə-sĭng, āl′yə-) n. 1.Visible or audible distortion introduced into digital information, such as images or audio signals, caused when a continuous line or transition is not smoothly captured or represented because of the low...
Aliasing is related to the discrete nature of the samples. When it is desired to represent a coarser version of the data using fewer samples, the optimal procedure is first to create a precise representation of the coarse data that uses every available sample, and then only to downsample ...
“Aliasing”(混叠)是信号处理中的一个重要概念,尤其在数字音频、图像处理和计算机图形学等领域。以下是对混叠的详细解释: 基础概念 混叠是指当一个连续信号被采样时,如果采样频率低于信号的最高频率的两倍(根据奈奎斯特-香农采样定理),则会出现高频成分的错误表示,这些错误表示会出现在采样后的信号的低频部分,导致原始...

混叠(Aliasing) 前面已经提到,数字信号相对于机械波和模拟信号来说,会损失一些位于采样点之间的信息。而其实,“混叠(Aliasing)”现象就是因为这种损失才出现的。 以正弦波为例,对于如下的这个频率为3Hz的正弦波,我们在其上采样3个点,也就是采样率为3Hz。由于采样点的位置是随机的,所以采样的情况可能就像下面这样:...
➤ 走样(Aliasing) 本质上来讲,走样是因为对函数(信号)的采样频率不足,或者说信号的变化速率远大于采样的频率,简单来说,在图形学中无法呈现所设想的效果,即称为走样。在计算机渲染中,由于绘制的图形在数学上是连续的,而渲染的像素点是离散的,从而导致在光栅化的三角形遍历阶段,将图形打散为像素时,会不可避免的...
