* Focuses on the underlying mathematics, especially the concepts of finite-dimensional vector spaces and matrix methods, and provides a rigorous model for signals and images based on vector spaces and linear algebra methods * Emphasizes discrete and digital methods and utilizes MATLAB(r) to illustrate these concepts * Combines traditional methods such as discrete Fourier transforms and discrete cosine transforms with more recent techniques such as filter banks and wavelets * Strikes an even balance in emphasis between the mathematics and the applications with the emphasis on linear algebra as a unifying theme
