Comments, with Reply, on “A New Approach to Recursive Fourier Transform”

M. Unser, M.G. Amin

Proceedings of the IEEE, vol. 76, no. 10, pp. 1395-1396, October 1988.



The commenter points out that the recursive structure of the running Fourier transform has been investigated by a number of authors not quoted by Amin in his work (see ibid., vol. 75, no. 11, pp. 1537-1538, November 1987). He also holds that the main idea behind the generalization presented in the third section stems from the properties of a yet more general class of features that can be computed using the same recursive structure. Additionally, he discusses Amin's treatment of the general form of a weighted running Fourier coefficient and points out drawbacks of expressing the weighting function as a sum of 2 M + 1 geometric series and treating each term separately. The author replies to the various comments.
