The cepstrum: A guide to processing
TL;DR: The power, complex, and phase cepstra are shown to be easily related to one another, and the interpretation and processing of data in such areas as speech, seismology, and hydroacoustics is discussed.

Two-dimensional spectral factorization with applications in recursive digital filtering
M. Ekstrom,John W. Woods +1 more
TL;DR: In this article, the concept of spectral factorization is extended to two dimensions in such a way as to preserve the analytic characteristics of the factors, and the resulting factors are shown to be recursively computable and stable in agreement with one-dimensional (1-D) spectral factorisation.
Journal ArticleDOI
The computation of two-dimensional cepstra
TL;DR: Two methods of computing the complex cepstrum of a two-dimensional (2-D) signal are explored and the relationship among the nonzero regions of a signal, its inverse, and its cEPstrum is explored.
