Presents manageable approach to unitary transform calculation and examines concepts in design, classification, and management of fast algorithms for different transforms in one-, two-, and multidimensional cases. This book illustrates methods to construct unitary transforms for best algorithm selection and development in real-world applications.

Describes the discrete Fourier transform, lifting schemes, integer transforms, the discrete cosine transform, and the discrete Hadamard transform. This book also examines the decomposition of the 1-D signal by section basis signals as well as new forms of the 2-D signal/image representation by direction signals/images.
