Features: This book is based on the perspective of engineering applications and primarily introduces the basic theory and typical applications of wavelet transform. The book consists of nine chapters. The part on the basic concepts and principles of wavelet transform introduces continuous wavelet transform, discrete wavelet transform, dyadic wavelet transform, multi-resolution analysis and orthogonal wavelet transform, multi-rate filter banks and wavelet transform of discrete sequences, wavelet packet algorithms, wavelet bases and sampling theorem, etc. The part on the typical applications of wavelet transform introduces singularity analysis of signals and image compression under wavelet transform, joint time-frequency analysis of signals and feature extraction, nonlinear filtering, etc. The book takes time-frequency analysis as the main line, introducing continuous wavelet transform, discrete frames, multi-resolution analysis, multi-rate filters, etc., in a step-by-step and progressive manner based on theoretical analysis. Each part of the book provides computational examples to facilitate readers' understanding of the content. This book is suitable for researchers and engineering technicians engaged in signal processing, image processing, pattern recognition, communication, seismic exploration, quantum physics, electromagnetic fields, mechanical engineering, fluid mechanics, fractals, optics, numerical computation, speech recognition, and robot vision. It can also serve as a reference book for teachers and students of relevant majors in colleges and universities.
