About this book A thorough guide to the classical and contemporary mathematical methods of modern signal and image processing Discrete Fourier Analysis and Wavelets presents a thorough introduction to the mathematical foundations of signal and image processing. Key concepts and applications are addressed in a thought-provoking manner and are implemented using vector, matrix, and linear algebra methods. With a balanced focus on mathematical theory and computational techniques, this self-contained book equips readers with the essential knowledge needed to transition smoothly from mathematical models to practical digital data applications. The book first establishes a complete vector space and matrix framework for analyzing signals and images. Classical methods such as the discrete Fourier transform, the discrete cosine transform, and their application to JPEG compression are outlined followed by coverage of the Fourier series and the general theory of inner product spaces and orthogonal bases. The book then addresses convolution, filtering, and windowing techniques for signals and images.
Jean Baptiste Joseph Fourier was a French mathematician, physicist and engineer, and the founder of Fourier analysis. Fourier series are used in the analysis of periodic functions. The Fourier transform and Fourier's law are also named in his honour. Graphically, even functions have symmetry about the y-axis,whereas odd functions have symmetry around the origin.
The area beneath the curve on [-p, 0] is the same as the area under the curve on [0, p], but opposite in sign. So, they cancel each other out! The area beneath the curve on [-p, 0] is the same as the area under the curve on [0, p], but this time with the same sign.
So, you can just find the area under the curve on [0, p] and double it! A periodic function can be defined on a finite interval,.
There is also a different normalization in use: They are then represented also by the series. Parseval's theorem usually refers to the result that the Fourier transform is unitary, that the sum or integral of the square of a function is equal to the sum or integral of the square of its transform.
