为在图像处理、计算器视觉、信号处理上所使用的一项技术。 高斯金字塔本质上为信号的多尺度表示法，亦即将同一信号或图片多次的进行高斯模糊，并且向下取样， 藉以产生不同尺度下的多组信号或图片以进行后续的处理，例如在影像辨识上，可以藉由比对不同尺度下的图片，以防止要寻找的内容可能在图片上有不同的大小。 高斯金字塔的理论基础为尺度空间理论，而后续也衍生出了多分辨率分析。-

As a technique in image processing, computer vision, signal processing is used. Gaussian pyramid is essentially a multi-scale representation of the signal, that signal will be the same picture multiple times or Gaussian blur, and down sampling, in order to produce multiple sets of different scales for subsequent signal or image processing, for example in the image the identification, can be compared to the picture at different scales, in order to prevent the contents may have to look for a different size in the picture. The theoretical basis for the scale-space Gaussian pyramid theory, but also spawned a follow-up multi-resolution analysis.
