Fundamentals of Wavelets

Most existing books on wavelets are either too mathematical or they focus on too narrow a specialty. This book provides a thorough treatment of the subject from an engineering point of view. It is a one-stop source of theory, algorithms, applications, and computer codes related to wavelets. This second edition has been updated by the addition of:

• a section on "Other Wavelets" that describes curvelets, ridgelets, lifting wavelets, etc

• a section on lifting algorithms

• Sections on Edge Detection and Geophysical Applications

• Section on Multiresolution Time Domain Method (MRTD) and on Inverse problems
