|Prof. James Nagy's book Deblurring Images published by SIAM|
|Published Date: 2006-10-27|
Professor James Nagy's book, "Deblurring Images: Matrices, Spectra, and Filtering" was published by SIAM Press. Abstract: When we use a camera, we want the recorded image to be a faithful representation of the scene that we see, but every image is more or less blurry. In image deblurring, the goal is to recover the original, sharp image by using a mathematical model of the blurring process. The book describes the deblurring algorithms and techniques collectively known as spectral filtering methods, in which the singular value decomposition -- or a similar decomposition with spectral properties -- is used to introduce the necessary regularization or filtering in the reconstructed image. The concise MATLAB implementations described in the book provide a template of techniques that can be used to restore blurred images from many applications.
