Transform image processing methods are methods that work in domains of image transforms, such as Discrete Fourier, Discrete Cosine, Wavelet, and alike. They proved to be very efficient in image compression, in image restoration, in image resampling, and in geometrical transformations and can be traced back to early s. The paper reviews these methods, with emphasis on Cited by: 9.

A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa.

The DFT is obtained by decomposing a sequence of values into components of different frequencies. The examinations are extended to fast algorithms for the computation of discrete cosine and sine transforms and to efficient computations of discrete Fourier transforms for nonequispaced data.

It is known that the discrete Fourier transform (DFT) used in digital signal processing can be characterized in the framework of the representation theory of algebras, namely, as the decomposition matrix for the regular module \${\mathbb{C}}[Z_n] = {\mathbb{C}}[x]/(x^n - 1)\$.

This characterization provides deep insight into the DFT and can be used to derive and understand Cited by: A good book on this subject for mathematicians, that does a better job of combining the discrete and continuous (but is much more advanced) is Claude Gasquet & Patrick Witomski's Fourier Analysis and Applications (Springer, ).

We have seen that a spectral representation of the signal, as seen in a spectrogram, contains much of the information we need. We can obtain the spectral information from a segment of the speech signal using an algorithm called the Fast Fourier Transform.

But even a spectrogram is far too complex a representation to base a speech recognizer Size: KB. Chapter 4 is devoted to fast algorithms, chapter 5 covers the two-dimensional DCT, and chapter 6 discusses the performance of the DCT with respect to such concepts as rate distortion. Chapter 7, on the applications of DCT, is by far the longest; it takes up nearly half of this book.
