Abstract
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.
