This book systematically introduces magnetic flux leakage testing principles and their applications in practice. Signal detection, collection, processing, the inversion of magnetic flux leakage defect and 3D imaging are discussed in detail with extensive project experiences, making the book an essential reference for researchers, developers and engineers in nondestructive testing.

This book illustrates utilization of fast transform, sparse representation and low rank analysis as tool in multidimensional signal processing and focuses on discrete cosine transform, optimization of double tree wavelet transform in coding and noise reduction, self-return compression perception of image signal. With orignal research results, the book is an essential reference for electrical engineering researchers and engineers.
