  H. Krim and A. Ben Hamza, Geometric Methods in Signal and Image Processing. Cambridge University Press, 2015.

 

Textbook This comprehensive guide offers a new approach for developing and implementing robust computational methodologies that uncover the key geometric and topological information from signals and images. With an emphasis on intuitive and application-driven arguments, this text covers not only a range of methods in use today, but also introduces promising new developments for the future, bringing the reader up-to-date with the state of the art in signal and image analysis. Covering basic principles as well as advanced concepts and applications, and with examples, this is an invaluable resource for graduate students, researchers, and industry practitioners in a range of fields including signal and image processing, and computer graphics.
