摘要

高阶谱在非高斯性、噪声和非线性问题中非常有用。这些性质已被证明存在于自然图像中。这产生了高阶光谱，特别是三阶，即双谱，是图像处理中的一个有趣的工具。本文介绍了高阶谱在信号处理中的应用及其在图像处理中的推广和应用，证明了图像是非高斯和非线性的。

Higher order spectra in image processing

Higher order spectra are very useful in problems where either non Gaussianity, noise and non linearities are important. These properties are proved to be present in natural images. This yield higher order spectra and especially the third order, namely the bispectrum, to be an interesting tool in image processing. This paper presents higher order spectra in signal processing and their extension and applications to image processing, where the images are proved to be non Gaussian and non linear.
